Abstract
The optical pattern recognition system of joint transform correlation has a disadvantage. It doesn't work under rotation of test object. In this work we show the experimental results of a technique for rotational invariant optical recognition which is based on a ring detector acting as filter. This correlator has the disadvantage of not present scale invariance of the objects under test. In addition, a theoretical analysis and simulation results are illustrated here with the use of an advanced mathematics software package.
