Tw. Wysokinski, APPLICATION OF THE PHOTOCHROMIC ADAPTIVE FILTER FOR ALL-OPTICAL IMAGE-PROCESSING AND ITS CHARACTERIZATION, Molecular crystals and liquid crystals science and technology. Section A, Molecular crystals and liquid crystals, 297, 1997, pp. 535-540
Several Photochromic Adaptive Filters (PAF's) made of organic photochr
omic materials embedded into a polymeric matrix are prepared. Transfor
mation Function (TF) of the photochromic filter is determined using a
simple, fast and accurate procedure. PAF's are used as opto-optic Spat
ial Light Modulators (SLM's) for image processing in the camera system
, which unites a Charge-Coupled-Device (CCD) camera with a photochromi
c filter. Change in the local absorption of the filter, caused by ligh
t radiation, is used to enhance the quality of the detected image.
