The dynamic possibilities of SLM based on electro-optic ceramics may be exemplified by a Sandia 256-element page com- poser operating at speeds up to 105 with a contrast ratio 1000:1. (U) According to Morozov, SLM with individual addressing may be built around paraelectrital memory- less PLZT ceramics with higher optical switching speeds of the order of tens of nanoseconds. (U) Fast space-time modulators may be built around monocrystalline segnetoelectrics, which are bi- stable and suitable for SLM with memory. Their mech- anism is based on the switching of spontaneous polar- ization, which is accompanied by essential changes in the optical properties of the crystal. Crystals of bismuth titanate (Bi4Ti3012) feature a small switching time of 1 Ilsec and a half-access voltage of 30 V. Large mono- crystals of high optical quality may be obtained from gadolinium molybdate, Gd2(Mo04)3, but their switch- ing times are about 0.1-1 msec, which is much greater than those of bismuth titanate. (U) Morozov states that ferromagnetic materials may be expected to provide a good basis for the design of high-speed SLMs that are matrix addressable by electrical voltage. Their true switching threshold en- ables the design of devices with over 100 x 100 re- solvable elements. There are published reports of SLM designs made of orthoferrites, such as DyFe03, YFe03, and YFeyGd103, y = 1-x, that feature the following parameters: 100 x 100 elements; maximal contrast, 400:1; and an optical effectiveness for the red line of a helium-neon laser of over 15%. Writing is done by local magnetic fields generated by current loops, one data bit requiring 10 nsec under a current of 1 A at most and a current loop diameter of 100-300 1.1.-m. Erasures and rewriting may be repeated arbitrarily; the storage time is also not limited. (U) The Soviets hope that new materials and semi- conductor injection lasers will enable them to overcome difficulties due to the appreciable absorption of ferro- magnetics in the visible spectrum and to the high cur- rents required for magnetic flux reversal. (U) Space-time light modulators based on multi- channel acoustic modulators are also feasible. The light beam is modulated and deflected by means of light diffraction on an acoustic wave excited by piezocrystals. A data array may be generated by means of a great number of individually addressable cells whose number corresponds to the number of modulation channels. The time sequence of m electrical pulses in n channels is transformed by the modulator into a running picture consisting of m-by-n elements. 32 Approved For Release 200001MANIM96-00788R0017000 (U) For parallel reading of a two-dimensional array, the pulse duration of the reading beam should be sufficiently short (about tens of nanoseconds) that a group of successively excited acoustic signals with one carrying frequency can be regarded as a stationary dif- fraction grid. According to Morozov, an amplitude spa- tial modulator has been designed with the following characteristics: number of channels n = 34, number of elements in each channel m = 128, power consumption per channel 0.5 W, and length of elementary acoustic beam 0.127 mm for modulator aperture 33.6 x 21.7 mm2. Modulator capacity is estimated as 1 Gbps. Mul- tichannel acoustic modulators require powerful pulse sources because the acoustic picture may be regarded as stationary only during a period of several nanoseconds. The major characteristics of some electrically controlled space-time light modulators are tabulated in Table VII. (U) Electrically controlled SLM input data arrived from the computer memory in electrical form into the optical processing path. Their major task is to quickly generate optical files; i.e., to prepare data for parallel optical systems. Thus, they serve as interfaces between electronic and optical channels of the computer system. As indicated above, their throughput may run into 1012 bps and more, but currently existing modulators exhibit a throughput of about 109 bps. Data input devices based on lines of memory-less modulators with individual addressing have good speed and may be addressed in one cycle; therefore, a line of 100 elements may have throughput of 109 to 1010 bps. 3.c. Multipositional Deflectors (U) (U) These devices are intended for changing laser beam spatial position according to a given law. In holo- graphic memory systems, deflectors are used for ran- dom access to memory locations. Deflectors may rely on electro-optic, acousto-optic, magneto-optic, and other physical phenomena. (U) Electro-optic discrete deflectors are multistep devices, each step consisting of polarizer, electro-optic polarization plane switch, and deflector. The polarizer linearly polarizes radiation. The polarization switch turns by 90 degrees the input beam direction of polar? - ization by subjecting it to an electrical or magnetic field. It may be made of material with a linear electro-optic effect (e.g., crystals of KH2PO4, NH4112PO4, LiNb0s, and many others) or a magneto-optic effect (Y3Fe502, CrBr3, etc.). The deflecting element performs spatial or angular separation of light beams with mutually or- thogonal polarization. (U) The basic parameters of discrete electro optic deflectors are as follows: number of deflection stages, ri a SG1A ved For Release 2000/0?MM-RDP96-00788R0017000 -f 71 7 s. _y 1. 12 it al in .er Dn er Ip tic :er ar- id. -tic 33, 112, ial or- 'tic 'es, TABLE VII (U) BASIC CHARACTERISTICS OF SOME ELECTRICALLY CONTROLLED SLM* CHARACTERISTICS SEGNETO-CERAMIC SLM ACOUSTO-OPTIC SLM MAGNETO-OPTIC SLM _ Modulating medium PLZT 7/65/35 grain, 2 p.m PLZT 9/65/35 grain, 2 imn PbMo04 Te02 YFe03 Modulating effect Double refraction Double refraction Refractive index Refractive index Faraday effect change change change change Addressing.

Discrete deflectors may be both one and two coordinate. (U) The deflection of light beams by means of acoustic waves is based on the possibility of periodic spatial changing of medium density by means of acous- tic waves, thus resulting in periodic spatial variation of the medium refraction coefficient. Acoustic waves form in the medium phase grid with a period equal to the wavelength. When the light beam passes, through a me- dium with a sinusoidally varying refraction coefficient, light diffraction occurs. If the light beam falls at the running acoustic wave under a certain angle, only first- order Bragg diffraction is observed. With alteration of acoustic wave frequency, the direction of the deflected 33 FOR OFFICIAL USE ONLY beam changes. Both liquid and solid isotropic and ani- sotropic materials may be used in Bragg deflectors. Te02, PbMo04, a-HgS, a-H103, Ag3AsSe3, and many other materials feature high opto-acoustic effectiveness. The following parameters characterize acousto-optic deflectors: beam deflection angle and resolution, speed, optical effectiveness characterized by the ratio of passed and falling radiation intensities, switching power, cen- tral (mean) acoustic wave frequency for which the Bragg condition holds, and the range of control fre- quency variations supporting light beam scanning. (U) According to Morozov, there is a practical possibility of building 2-D multipositional deflectors with ? lir positions and switching frequency of up to 10 MHz and more higher, provided they are built of the best materials: LiNb03 for electro-optic deflectors and a-H103, PbMo04, and Te02 for acousto-optic deflectors. , SECRET Approved For Release 2000103/613F:(COVDRbi,14300088R001700020003-0 Approved For Release 2000/08/08 : CIA-RDP96-00788R001700020003-0 CPYRGHT Puc. 33, Puc. 16. 2 1111111111111111111111111111111111111111111111111 1111111111111111111111111111111111111111111111111 Puc. 32.
