Dual-mode composite infrared electric control liquid crystal micro-lens array chip

Abstract

The invention discloses a dual-mode composite infrared electric control liquid crystal micro-lens array chip which comprises a chip shell, an electric control light divergence liquid crystal micro-lens array and an electric control light condensation liquid crystal micro-lens array. The electric control light divergence liquid crystal micro-lens array and the electric control light condensation liquid crystal micro-lens array are in cascade coupling connection to form a dual-mode composite electronic speed controller framework. The electric control light divergence liquid crystal micro-lens array and the electric control light condensation liquid crystal micro-lens array are both arranged inside the chip shell, are tightly attached to each other and are connected with the chip shell. The optical axis of the electric control light divergence liquid crystal micro-lens array coincides with the optical axis of the electric control light condensation liquid crystal micro-lens array. The light incident plane of the electric control light divergence liquid crystal micro-lens array and the light emergent plane of the electric control light condensation liquid crystal micro-lens array are exposed out through an opening in the top face of the chip shell and an opening in the bottom face of the chip shell respectively. The dual-mode composite infrared electric control liquid crystal micro-lens array chip is compact in structure, capable of being used for forming various light beam forms, better in light field adaptability compared with a conventional electric control liquid crystal micro lens, high in control precision and capable of being coupled with a conventional infrared optics and optoelectronic mechanical structure easily.
