Abstract
Coherent optical noise can be suppressed by sending the desired signal through a number of channels and combining the result at the output. Channels coded by means of spatial frequency are particularly convenient for optical processing systems and offer some advantages additional to noise reduction. The mechanism of noise reduction is described for such spatial frequency diversity systems, and some experiments are described that illustrate noise reduction and multiple filtering possibilities of this technique.
