Abstract

The operation of a scanning optical correlator is described and demonstrated. The device is shown to combine the advantages of a coherent correlator, which makes preprocessing operations easy to realize, with the advantages of direct-image-casting correlators, which are insensitive to setup misalignment and imperfections and do not require the preparation of any filter. For some applications, these attributes may compensate for the fact that scanning optical systems are inherently slower than parallel, frequency plane processors.
