Paper Abstract

Estimating the shape of a target can be an important task in long range surveillance applications. In certain situations obtaining an adequate spatial image of a target can be problematic, especially when the object size and distance requires an exceedingly large receiving aperture, or when significant atmospheric turbulence exists between the target and the receiver. This paper discusses a simple sinusoidal dithering laser illumination scheme that is capable of recovering low spatial frequency information about the object based on the reflected flux. The approach is analyzed in the presence of the corrupting influences of beam jitter. The performance of the method is tested through simulations and laboratory experiments.
