Design for the Spectrum Feature Analysis Experiment ofIFT & FT Optical Fourier Transform Using Lens Based on 4F Optical System

分析了基于4F光学系统的透镜FTI、FT变换光学的数学表述,指出其参数所表征的物理意义;据此提出利用若干等焦距透镜建立变换光学频谱特征分析实验的构思,利用CCD器件和计算机进行采样、分析,阐述d0试件几何孔径等因素对其变换光学频谱特征的影响.

The function for IFF ＆ FF optical fourier transform using lens based on 4F optical system is analyzed so that point out the physics signification, which its parameters include and put out the design for the spectrum feature analysis experiment use the lens with the same focal length, combining with the computer and CCD sampling ＆ analysis technology. Tne technology has an important to explain the case, such as do and geometry radius of lens etc, lead to the difference of the optical fourier transform spectrum feature.
