The objective of this research is to study the functional relationship between amplitude and phase images, using a sinusoidal test function. Amplitude and phase sine wave gratings were produced and scanned. It was found that the phase image closely reproduces the amplitude image for low spatial frequencies, but the accuracy of reproduction falls off at high spatial frequencies.
