ABSTRACT TEXT:
The
electrographic process now widely apply in technology of an
recording of the information. It is applied in such widely
used devices, as the laser printer and copier. The essence
of electrographic process consists in that, what the high-resistance
semiconductor at first has been charged in an electric field,
and then on it is projected the image. In those places that
was irradiated by light, will be a photoinduced conductivity
and the charges on surface of semiconductor will be neutralized.
As a result of it on a surface of the semiconductor appear
invisible image that is formed by allocation of electric charges.
In places where exposure was high - charges will be absent,
where exposure was minimum- amount of charges will be greatest.
Visualising of electrographic image is realized by various
methods, for example in the copier of a particle of a paint
adhere to charged sites and the image becomes visual.
We
has considered the new process of visualization of the electrical
image at the expense of a diffusion of tungsten under an operation
of an electric field through the chalcogenide glasslike semiconductor.
The ions of tungsten diffusing into the semiconductor, has
formed chemical combination with selenium and this combination
is not dissolve any more in the etchants. With the result
that after an etching of the semiconductor we obtain the phase
image, the depth of relief which depends on an amount of incidence
light on an this place. We has considered the dependence of
a velocity of a diffusion from magnitude of an electric field
and exposure. We has considered also resolution power of process
and dependence its from temperature. We show, that the photographic
sensitivity of such electrographic process achieve 10-4
J/sm2, and resolution power achieve 1500 mm-1.
The
above permit come at the conclusion, that electrographical
process can be used for producing holographic optical elements.
