摘要：

We present a development of the method of synthesized phase objects (SPO-method) (P. V. Yezhov, et al. Opt. Exp. 20, 29854 (2012)) for the phase-only rotation invariant pattern recognition. It has been performed a comparison of correlation signals for a set of amplitude objects under their rotation by using the standard and SPO methods, by applying the Fourier-Mellin transformation. The results of both calculation and optical experiments carried out using an optical-digital correlator with SLM in the Fourier plane have been presented.
