Application of the Photochromic Adaptive Filter for All-Optical Image-Processing and Its Characterization
Several Photochromic Adaptive Filters (PAF’s) made of organic photochromic materials embedded into a polymeric matrix are prepared. Transformation Function (TF) of the photochromic filter is determined using a simple, fast and accurate procedure. PAF’s are used as opto-optic Spatial Light Modulators (SLM’s) for image processing in the camera system, which unites a Charge-Coupled-Device (CCD) camera with a photochromic filter. Change in the local absorption of the filter, caused by light radiation, is used to enhance the quality of the detected image.
