OSCAR is an optical FFT code used to calculate the steady state optical eld circulating in Fabry Perot cavities. The code can integrate non-sperical mirrors and any arbitrary input elds. Recent applications for OSCAR have been: calculation of thermal lensing eect and calculation of diraction 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 modied OSCAR code to suit specc purposes.

it is useful for my research work

图像经过二维傅立叶频谱分析后，用此函数可以求取频谱的环向、楔向特征。在图像分析中具有较大用途。(After two-dimensional Fourier spectrum image analysis, this function can be used to strike a spectrum of the ring, to the characteristics of wedge. In the image analysis with a larger purpose.)
