摘要
将物体的复振幅透过率分解为复数傅里叶级数,则在白光信息处理系统中,物体的第n级频谱在输出面上产生的光场复振幅,就是该级数中相应的系数.用这种新方法分析了振幅光栅对光栅编码位相图片的假彩色的调节作用,求出了精确解,改进了已有文献的不足之处,并分析了位相光栅对假彩色的调节作用.
It is proposed that complex light amplitude distribution of the n-order fourier frequency spectrum on the output-plane is the relative coefficient of the complex fourier series which represents the transmittance of the object on the inputplane. Based on this new computation method, the theoretical explanation of the pseudocoloring of an encoded phase-picture and the adjustable pseudocoloring by using a grating is made satisfactorily and exact solutions are presented.
