Abstract

A white light incoherent imaging system is used as a multichannel processor that allows the computation of the amplitude and phase of complex-valued Fourier components of an achromatic object. The pupils of the system consist of two slits which introduce the modulation of a fringe pattern by the complex-valued information. The demodulation is performed by using a CCD line and a microcomputer that releases the amplitudes and phases. Alternative incoherent systems are suggested for self-luminous objects.
