Since 1970 the subject of amorphous semiconductors, in particular silicon, has progressed from obscurity to product commercialization such as flat-panel liquid crystal displays, linear sensor arrays for facsimile machines, inexpensive solar panels, electrophotography, etc. Many other applications are at the developmental stage such as nuclear particle detectors, medical imaging, spatial light modulators for optical computing, and switches in neural networks (1,2). 

Nowadays, polymeric photoconductors may be used in electrophotography, microfilms, photothermoplastic recording, spatial light modulators, and nonlinear elements. The combination of photosensitivity with high quality electrical and mechanical properties permits the use of such materials in optoelectronics, holography, laser recording and information processes. The applications of the various types of polymers were reported in the final parts of the relevant items in the earlier sections. Here, we will briefly analyze the common features of photoconductive polymer applications. The separate questions of each type have been dealt with in some books and papers [3, 11, 14, 329].

The spatial light modulator used in our system is a modified DMA chip by Texas Instruments (DMD 0.7 XGA 12° DDR). The array consists of 1024 x 768 aluminum coated individual micromirrors of 14p,m x 14p,m each, capable of 12° tilt relative to the diagonal. Mirrors are individually addressable through a driver circuit available from the manufacturer. For IR applications, the original glass window needs to be replaced with an IR-transparent window. We have developed the technology to mount coated ZnSe windows on Texas Instraments DMA chips and preserve long lifetime of the chip.

Liquid crystals have found an important place in modem life. Just look around we see them in our clocks, computer displays, TV screens, telephones and calculators, car dashboards, photo-cameras, etc. Other applications include slide projection systems, spatial light modulators, temperature sensors and even liquid crystal lasers. In all these technical innovations, which appeared over the life of only a single generation, liquid crystals occupy a key position. This is because they consume a barely perceptible amount of energy when they change their state under external influences such as temperature, electric field, mechanical stress or whatever. In addition, there are very important biological aspects of liquid crystals. 

We use for this application a phase reflective spatial light modulator (SLM) and a fixed transmissive diffraction grating to select the corresponding output wavelength from an set of channels in the input, as shown in Fig 11. The active element of the SLM is a Ferroelectric Liquid Crystal (FLC) with a low switching time (less than 50 ps) that allows a real time...
