Abstract

Inaccurate positioning and low-quality optics introduce position-dependent phase errors into coherent optical processors. For the inspection of composite objects, these lead to interference effects at the correlation plane and in particular the occurrence of blind spots through destructive interference. This in turn may result in a misinterpretation of the output. The circumstances under which this might occur are experimentally investigated.
