用间类最大距离法自动求取多张图像的阈值，MATLAB实现(With the largest distance between the type of multiple images automatically strike the threshold, MATLAB realize)

OSCAR is an optical FFT code used to calculate the steady state optical field circulating in Fabry Perot cavities. The code can integrate non-sperical mirrors and any arbitrary input fields. Recent applications for OSCAR have been: calculation of thermal lensing effect and calculation of diffraction loss and cavity eigen modes for mesa beams. One great advantage of OSCAR is the simplicity and exibility of the code, everyone with only minimal knowl- edge of Matlab can easily modifed OSCAR code to suit specfic purposes.
