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

The function for IFT FT 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. The 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.
