| Abstract: | We present the nonlinear joint transform correlation computer simulation results and the optical experimental results of the scale and rotation varying objects, as well as the statistical experimental results of the autocorrelation peak distribution of the object. The given experimental results show clearly that the optical experimental system is a nonlinear joint transform correlation system and the distribution of the autocorrelation peak is to some extent random. Correlation peak signal intensity of the nonlinear joint transform correlation system has no obvious variation when the scale variation of the object is less than 10% or the rotation angle variation of the object is less than 5 degrees. |
