3D imaging: wave front sensing utilizing a birefringent crystal

Abstract

Utilizing a rotatable thin birefringent crystal and two polarizers, the three-dimensional (3D) wave front of any light wave can be measured conveniently. In first experiments phase-front distortions as small as 15 &mgr;m are detected with a dynamic range of 3 mm and a spatial resolution of 50 &mgr;m. Such a dynamic range and spatial resolution exceed the… (More)
