ABSTRACT:
An electro-optic sensor for precise, direct and continuous measurement of the angular displacement between two bodies. A linear array of photodetectors is disposed on a planar surface mounted on the first body parallel to the axis about which the displacement is to be measured. The line of the array is perpendicular to this axis. A light source disposed on the planar surface near the photodetector array transmits light through optics to a reflecting reference flat mounted on the second body. The optics collimates the transmitted light and causes the reflected image of the light source to be spread into a line on and perpendicular to the photodetector array. This line image moves along the linear array as angular displacement occurs between the two bodies. No mechanical moving parts are required in the sensor.
