Pattern recognition with spatially incoherent holographic correlators is described. Their performance is improved by optimizing the optical layout and preprocessing the reference image. Compared with coherent holographic correlators the incoherent ones are much more tolerant of mechanical errors, optical aberrations and dust; also, they work without spatial light modulators.
