An Interactive System for Digital Optical Image Processing
The coherent optical processor (COP) was introduced an ultra fast image and and general data processor working with the ‘speed of light’, or with a realistic estimate, performing about 1014 multiplications per second /l/. On the other side the COP shows two major handicaps. It has a rather poor signal to noise ratio of about 20 to 4, depending on the quality of the lenses and surfaces /l/. Another problem arises at the data input stage where the data should be presented on transparencies coded as amplitude transmittance in a range between 0.0 and 1.0. To avoid the photographic process various incoherent/coherent and electro/optical transducers have been developed /2/.
