Patent ID: 7483601

Claim:
A polarization maintaining optical device, comprising: a polarization maintaining optical array; a microlens array to receive light from the polarization maintaining optical array or to couple the light into the polarization maintaining optical array; another microlens array; another polarization maintaining optical array optically coupled to the other microlens array; and a beam steering device to optically couple the microlens array and the other microlens array, wherein the beam steering device comprises: one of only a single microelectromechanical system (MEMS) mirror array and a single liquid crystal deflector array, optically coupled to the microlens array; and a bulk mirror optically coupled to one of the single MEMS mirror array and the single liquid crystal deflector array and disposed between the polarization maintaining optical array and the other polarization maintaining optical array and opposite to one of the single MEMS mirror array and the single liquid crystal deflector array.
