Abstract

We have performed laboratory experiments that demonstrate that unspeckled images of coherently illuminated, diffuse objects can be formed from measurements of backscattered laser-speckle intensity. We show that images revealing gross target features can be successfully recovered with relatively few snapshots of the observed laser-speckle pattern.
