Title:
APPARATUS FOR STRESSING OPTICAL CHARACTERISTIC
Document Type and Number:
Japanese Patent JPS6254284
Kind Code:
A
Abstract:
An optical system for selectively enhancing and/or suppressing the spectral intensity of components in an object beam, is disclosed. Initially, a forward transform operation such as, for example, using Fourier optics (9), is applied to an input beam which contains a complex function characteristic of an object. The resulting Fourier transform is applied to a non-linear optical medium (11) and interferes with a reference beam (12) to form a hologram in the medium (11). The hologram is then read-out (13) and an inverse transform operation (15) is performed on the resulting output beam (14), to provide an output optical beam which contains, for example, selectively enhanced intensity components and/or selectively suppressed intensity components.
