Abstract

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/.
