Optical two-dimensional servo-loop for laser beam stabilization and/or position encoding |
摘要 |
The present invention pertains to an electrooptical tracking system. The invention includes means for producing a coherent beam of light and means for deflecting the beam of light. The deflecting means deflects the beam of light with respect to a first and second direction corresponding to a first signal, with the first direction being approximately orthogonal to the second direction. The deflecting means also produces a second signal corresponding to the deflection of the light beam by the deflecting means. The location of the light beam is determined by means for detecting the location of the light beam with respect to the first and second directions. The detecting means is aligned to receive the beam of light that has been deflected by the deflecting means. The detecting means also provides the first signal to the deflecting means corresponding to the detected location of the light beam with respect to the first and second directions.
