Abstract

Recent advances, including binary phase-only filters (BPOF) implemented with suitable real-time devices, have enhanced the potential of coherent optical correlation for pattern and object recognition and object location functions which are important in machine vision applications. Hybrid (optical/electronic) systems performing complex vision operations such as recognition, location, and discrimination at attractive rates are enabled by these developments. Computer simulations and matching experimental runs investigating the performance of BPOF correlation on video images of actual industrial objects have been performed and are reported. The results are not exhaustive and they do not provide the solution to a particular machine vision problem, but they do indicate the high potential of hybrid optical/electronic systems for this type application.
