Abstract

A laser radar system for three-dimensional lensless imaging is analyzed in theory and by experiment. Three-dimensional imaging is accomplished by making use of the relationship between the wavelength dependence of an object's scattered light and its three-dimensional Fourier transform. The concept is demonstrated by obtaining a three-dimensional image with a charge-coupled device detector array and an argon-ion laser with a tunable intracavity etalon.
