Abstract
Interference techniques can be used to measure both the amplitude and phase of optically generated Fourier transforms. Because phase information is recovered by observing an interference pattern, source coherence can significantly influence phase accuracy. System performance is analyzed using simple test functions and the phase error is estimated in terms of the source transverse coherence length and space-bandwidth product of the input function.
