Optical systems for combined 1-D image-orthogonal Fourier transform processing.
A number of spherical and cylindrical lens combinations are described to achieve a 1-D image and an optical Fourier transform normal to the imaging direction. Both output distributions must be coplanar. Optical features dealt with are the image and transform magnification, lens separation, and input-to-output plane distance. Variable magnification setups with fixed focal length combinations are given.
