The binary amplitude modulated phase only spatial filter (BAMPOF) is studied and different filters are compared to access the BAMPOF′s performance. The study shows that the BAMPOF has good features regarding the sharpness of the correlation peak, Horner efficiency and noise tolerance. So, the applications of it in the optical pattern recognition is promising.
