Design an active imaging system using squeezed state light

Abstract

Squeezed light is an important non-classical light field. In this paper, we demonstrated a designed active imaging system which use squeezed state light instead of coherent light as light source. The squeezed state light is generated by utilizing the degenerate optical parametric amplifier based on periodically poled KTiOPO4 crystal. In order to obtain better imaging results, microlens arrays are used for homogenizing the squeezed light. We describe experiment setup and present some design result.
