Image subtraction based on interference and filtering
This paper presents a new method of complex amplitude subtraction. The lens forms the Fourier transform spectra of two transparencies, Young's interference fringes formed by the identical image of the two transparencies are filtered with slit. The differential image of the two transparencies is obtained on the output plane.
