TITLE: Measuring frequency fluctHot-imby a delay-line method
I O)nl
SOURCE; Radiotekhnika i slok-tronika, v. 9, no. 9, 1964. 1626-1633
TOPIC TAGS: frequency fluctuation, delay line, aquare law detector, signal
detection
ABSTRACT: Measuring fluctuation of the frequency of oscillations by a delay-
lino methrod with the use of a square-law detector is theoretically considered. A
correlation function of the datcctor-011tIJUt signal Is developed. The output-signal
spectrum is described by a formula derived from a Wiener -luiinchin theorem; the
formula holds true for any delay time (no limitation of the phase drift during the

~ABSTRACT: This Author's Certificate Introduces an electron optical transducer for
,spatial displacements of an image of a luminescent object. The device contains an
'[objective lens, a color selective plate which proJects an Image of the objective
:onto two rotating cylindrical modulation lattices in the channel for the azimuth
and angle of elevation, a sensing element and an electronic unit which analyzes the
signals in each channel. The device Is designed for giving information on displace-
ment of the image of an object in the direction of propagation of the lLuninaur, flux
~(approach or withdrawal of the object or change in the focusing of the Objective
leng). The axis of rotation of one of the modulation grids is offset with respect
~to the geometric axis of the grid so that there is art additional amplitude m-dula-

ABSTRACT: The authors examine the possibility of reducinix -the line width of a la-
ser by using an atomic bean in a direction parallel to the front or tir wave in the reso-
nator. Since population inversion cannot be produced In this case by allowed opti-
cal transitions,, they propose the use of the IBO* pulse method, wherein the atomic
beam passee,through a light ray whose frequency equals the excitation frequency
necesear7 fdr the atom to go over into a long-lived excited state. To avoid the
difficulty raised by the possible deviation of the lazing frequency from the central
transition frequencyp the atomic bean Is meae to Interact with the light beam gener-
ated by the laser Itself. A diagram of such a laser Is shown In Fig. I of the tn- ',
closure. Its asseuttal part Is a quutum amplifier operating at the transition fre-&
quency. It to possible to use a semiconductor quantum amplifier In the cas* of Ca

between heterodyned waves to theoretically explored for various cases of
ncncoherent (ordinary lightj and coherent (laser, TEMOO) waves. In the case of
plane waves, the beat amplitude depends on the wave polarization and is directly
proportional to the area of the converter; two subcases of different and

(a codocal-resonator laser) Is almilar to the planar case, Also, a formula for
