Optical system for measuring orientation with corner cube and mask

摘要

The system has an optical cube corner (CO) arranged on a mobile object. An inlet face of the cube corner comprises a mask, which is formed in shape of a parallelogram. Each side of the parallelogram comprises a marking to identify images of the mask formed on a photosensitive matrix sensor (D) by reflection of intersection of a projection of the mask and a projection of the image on the sides of the cube corner with respect to center of the cube corner. The markings are formed in form of projections and/or notches.
