MULTI-POSITION POLARIZATION DEFLECTOR Russian patent published in 1997 - IPC

FIELD: optical engineering. SUBSTANCE: device has sequence of $$$ and $$$ binary deflectors of x and y-deflection. Device is also provided with m-1 telescopic members and m-1 auxiliary switches of ray polarization. Binary deflectors of X and y-deflection are provided in definite sections of two double-refraction members of x and y-deflection, respectively, placed between two groups of telescopic members of double magnification, the optical axes of which are tuned through 180 deg. by mutually perpendicular deflecting surfaces. Auxiliary switches of ray polarization are positioned in front of every telescopic member and at device output. EFFECT: improved spatial communication of optical ray. 2 dwg, 1 tbl
