ABSTRAM The present paper deecribes briefly the technique of proparation of
optical diffractioa gratings at the State Optical Institute Imeni
6.1,, Vavilov and discusses In detail the optical characberiatics of
these gratings in the ultraviolet, visible and near infrared spectral
regions. The technique of preparation of gratings was fully described
in References 1, 2. Rehalette gratings for the waveler~gtbB
2.5-600 ~ were d as cribed in a paper pres anted at the .14:h All -Union
Gonferance on 3pecitroscopy (Ref 3). The gratings are -?repared by
mooze of a screw-motion ruling machine (Fig 1) which can produce
gratings of 160 x 150 mm area with 1200, 600, 300 and 200 lines/=.
This machine does not differ from the majority of machines deeribed
in literature. Fige 2 and 3 show certain details of the carriage of
Card 1/2 the ruling machina at the Institute. A typical profile of a diff mction
grating is shown in Fig 4. The lower part of the figure shows

Diffraction Oratings from the State optical Institute
an slectron microscope image of a grating with 1200 lines/m. The
optical characteristics of the gratings produced are discussed as well
as the sources of certain errors. 'Me, revolving power of better
gratings roaches 600 000. Tho relative intensity of Rmil&rdls "rhoBts"
in tie first order of gratings with 600 lines/im is about 0.1%, and in
better gratings it may be only 0.01%. The gratings of 'the State
Optical Institute produce a high concentration of light in a given
direction. Thus gratings with a stop-like profile,mith a slope
of the working edget of 5-100, concentrate in the maximz up to 85%
of the total reflectod light, which is near the theoretical limit.
A characteristic change In the polarization properties of gratings
was observed in tho) region of the maxilmun light concentration. On
the short-wavelength side of the maximum the compcaeat with electric
vector vibrations parallel to the grating lines is the more intense,
and on the long-vavelength side of the maximum the component with
electric vector vibrations perpendicular to the gratin; lines is stronger

ABSTRAM Light bows diffracted by a &rating may interfere with one another
provided they are cohoront. As authors observed interference between
beam diffracted by a plans or a concave grating. Ae apparatus used
in experiments with plano gratings is shown schematically in Fig 1.
Two diffracted bows (i and 2 in Fig 1) were reversed by plans mirrore
and, after second diffraction at the grating they wero focusod by an
objective, as shown In FIG 1. When tne mirrors are placed at certain
angles interforene* bands are obrorved at the focus. rho o---tical
system of an Interferomater wild a concave grating is shown in Fig 2.
A light beam from a lamp I passes through an aperture 2 and after
reflection from a half-silvered glass plate 3 falls on a concave
$rating 4. Diftracted bo&ms of the first order are ravers-bd by plane
mirrors 5 and after a nerond refraction convergo at a point 6 at which
interference may be ob-sorved visually. -the system can be used for

A wide central spot was due to light reflected fram a grntin~ as if
from a concave mirror (toro-order beam). The weaker spots are due to

TITLE: An Experimental Study of the Spectral Distribution of
the Intensity of Polarized Light Diffracted by a Grating
PERIODICAL: Optika i spektroskopiya, 1961, Vol.10, No.1, pp.104-112
TEXT: The authors studied the reflection of monochromatic
(X = 0-4 to 1-711) polarized light by diffraction gratings ruled
an thin metal layers (line profiles were stepped). The reflection
coefficients were measured, using apparatus shown schematically in
Fig.l. A diffraction grating 7 was illuminated by a parallel
beam of linearly polarized light from a grating monochromator 2
(3 and 4 are, respectively, the exit slit of the monochromator
and a lens). The diffracted light was focused by means of a
lens 8 onto a photocell 9 . The reflection coefficients were
found as the ratios of the intensities of a bea. diffracted by a
grating and a beam reflected by a plane aluminized mirror 6
placed in the beam instead of the diffraction grating. An
incandescent lamp 1 was used as the source of light. A Rochon
prism 5 was used to polarize the light. The photocurrent of

An Experimental Study of the Spectral Distribution of the

the cell 9 was measured with a mirror galvanometar 10. In all,
40 plane gratings, with 200, 300, 600 and 1200 lines/mm, were
studied. The spectral distributions of the diffracted light
(Fig.2, 3 and 5) were displaced relative to one another when (a),
the elect-ric vector of incident light was parallel to the grating
lines and when (b) electric vector was normal to the grating lines.
The distribution for case (a) was always displaced towards
shorter wavelengths with respect to the distribution for case (b).
The displacement was proportional to the wavelength and inversely
proportional to the grating constant (Fig.4). The displace
produced a change in the polarization of the diffracted light
(the apparatus used for measurements of polarization is shown in
Fig.7 and the results are plotted against wavelength in Fig.6).
Replica gratings made of polymethyl methacrylate or gelatine did
not exhibit this displacement which was characteristic of metals

ABSTRACT: The characteristics of concave diffraction gratings with step profile rul-
ings are discussed. Conventional gratings cozwonly employed In spectroscopy, parti-
cularly in the wavelength reCion below 1000 9, arc characterized by Vshaped lines
separated by flats (a in the figure - see Enclosure). Such gratings in the short
wavelength-region.are characterized by low efficiency as reggrds concentration of
light: about 20% in one of the first orders. In practice, owing to unavoidable ir--,
regularities, the actual profile has 'the appearance shown In b, so that the eifici-
oncy is further reduced. In the present paper there are discussed concave gratings
with a line profile of thp type shown in c. Theoretically such gratings should be

more officient.,,Tho angle of inclination a must be of the order 30. Gratings of thJs
type have beeniruled on aluminum and have proved capable of concentrating up to 85%
of the reflected radiation in onejordej% Httorto, such gratings have not been ruled
on glass owing ~o thfD meqianical 4iffieulties involved. These difficulties stem
from the faci tAat the grooves mu#t be very shallow in view of the small value of
the angle a and the fact:tbat the.angle Ot must be maintained constant over the
curved surface pf the gratings. Tpe authors have ruled and tested concave gralings
of this step type on aluminum coated om glass (1200 lines/mm) and on Fl glass witil
300, 600 and 1200 lines/mm and angles U from 30' to 40. A special set-up was t1evel-
oped'for visual determination of the location of maximum concentration. The euperi-
mental gratings were tested in a number of short wavelength spectrographs and
yielded satisfactory results, i.e., resulted in a significant reduction of the ex-
posure time. he results of measurement of the efficiency of the gratings In .he

ABSTRACT: This is a continuation of an earlier study of the distribution of energy
im the spectrum of a diffraction grat,',ng (07t. i spektr. v. 19, 417, 1965) where it
was observed that the sum of the reflection coefficients in all orders of the spectra
differs with the polarization. The present paper reports the results of an experi-
mental check of the previous calculations. The experiment was made with-two gratings
of 600 lines/mm, cut on alvminum and having lines with step-like profiles. The facesi
of the steps were at an angle of -120", and the face with the smaller slope made an
angle of 10* or 230 in the two gratiq;s) respectively. The apparatus used to measure
the reflection coefficientep for near.-normal incidence) was the same as described by
the authors earlier (ZhPS v. 2, 402, L965 and Opt. i spektr. v. 10) 104y 1961). The
measurements were made In the X/d (grxting constant) range 0.35 - 1.8. Me results
show that for the parallel component -the sum is close to 100% in both caties in the
case of the perpendiculAr componentj 'the sum decreased sharply at vavelejigt~s equal

t-, latter method was limited to visible light. The behavior of the suml of the re-
flection coefficients, and also its dependence on the depth of the grating line, the

the two. Orig. art. has: 1 figure.

ABSTRACT: A comparison of the operation of two types of iron ladles-
UZTM and Klimg types with a spherical bottom and Bamag
type with a flat bottom is compared. Main characteristics
of the ladles are given in the table and fig.l. Service
life of the flat ladle linilig is on average 60 days during
which 60,000 tons of iron is transported, Hot repairz of
Bamag ladles present no difficulties, The lining waars
out uniformly along the height of the ladle. The n?moval
of worn lining can be done in 2 hours by cne man using a
Crelle (Tig.2). Relining requires 6 man shifts. The,
service life of UZTM and 'ZI:L* ladles is 40-45 days during
which th~iy transport 25-30,000 tons of iron. The lining

of these ladles errodes non-uniformly (with the train
movement) due to the spherical bottom, The removal of
the old lining requires 8 man shifts and the relining
24 man shifts. It is conclu,"-~.d that the Bamag type ladles
are coasiderably more economical and easy in operation.
The manufacture of flat bottom ladles with a conical top
of a round cross-section is recommended. There is
1 table and 2 figures.

TITLEs Adjustment of Linear Triangulation-by the Method of Conditiomal
Obsorvations
PERIODICALs Geodeziya, i kartografiyat 1960p Ir 1, PP 8-17 (USSR)
ABSTRACTs In adjusting geodetical nets of arq type, especially triangulax
seriest it.is convenient to use the surface method in a pe-
culiar way. One variant of this method, which should be bettor
called.the diagonal method, is investigated here. For reasons
of clearness, this. viethod is shown by the example of adjustijig
a series of plane triangles (Fig 1). The following independeat
conditions are assutkedt the diagonals calculated for the ad-
justed values of tho meanured triangle sides must be exactly
equal to the length of the same diagonal obtained by the
solution of the Inverse problem by means of the final co-
ordinates of the trilateration points. Condition (1) for the
triangiAsr surfaces is written down. It can only be complied
with if the changes &P of the triangular surfaces comply with
condition (2). With the une of (2), the relation between the,

Adjustment of Linear Triangulationby the Method of Conditional Observations
the abrroations of the measured sides can be determined. Thij
use of this relation is one of the main characteristics of the
method described, When using this method it is not necessarr
to calculate angles or consult ta,bles. The formulas for cal.
oulating the point coordinates by the measured triangle sides
were found by S. A, Butler and V., A. Polevoy (Refut Footnote
on p 9)* More convenient formulas are given here for the pra%--
poses mder reYiew. They permit a simultaneous calculation (if
the point coordinates and the coefficients of the conditional
equations of the diagonals; The conditional equations of the
diagonals ars solved in common by the method of least aqua-roe.
Tables 1,20t and 4 show the order, details, and control of
the calculations. They present an example of adjusting a
sarise of triangles with measured sides. Finallyq the difference
ia using the diagonal method for adjusting a central systgm
with respect to the case investigated is pointed out* The
paper by G. A. BUTMiBtrov (Ref, Footnote p 8), and the formula
by Geron, are mentioned. There are 3 figures, 4 tables, and
