Semiconductors are believed to be quite promising among systems, which are potentially capable of replacing silver-containing photosensitive materials (see, for example, Sviridov and Kondratyev, 1978 Kiess, 1979). A semiconductor-electrolyte interface is directly used in certain techniques of producing latent and visible images.

Photoresists are divided into two classes. Negative resists are materials whose solubilities are decreased by exposure to actinic radiation. The image is then developed by selectively dissolving the more-soluble, unexposed portion of the film. This basic process was invented 150 years ago and it is used in the manufacture of printing plates (63). Positive resists, on the other hand, are materials whose solubilities are increased by exposure, so that in development the exposed portion of the film is removed. The history of photoresists is described in Kosar s book (63), which is also an excellent review of the history of many photosensitive materials. 

In photoconductive pigment electrophotography, the photosensitive material is incorporated into toner particles that are dispersed in an insulating liquid or softenable resin. The effect of the exposure is to create a variable charge on toner particles, w hich are then displaced by a field. The more common variants of this process are photoelectrophoresis and migration imaging. In photo-... 

TEs are those penetrating through a thin specimen that are focused into images on a phosphor luminescence screen or on a photosensitive material. Some of the PEs are absorbed by the specimen and are grounded as a current. If there is no ground connection, the specimen will charge up.

Fig. 24. Real images of the Fomier holograms recorded in our photosensitive material.

In order to compare our photosensitive material, we use the SO-253 film from Kodak to make the Fourier hologram of the text and the reconstructed real image is show in Fig 25 It is important to note, that the amount of text in Figs. 24 and 25 are different because we use 1 inch of diameter lens in one optical setup and 2 inch of diameter lens in the optical setup used in order to illuminate the photosensitive material. Another difference is that the SO-253 film has its sensibility at the line X=633 nm so we record the Fourier hologram with this wavelength and we use the same wavelength to reconstruct the real image.
