    Power/position monitoring

    May 1, 1996
    The D2000 Smart Mirror assembly allows users to monitor power and position of lasers in real time by passing a small percentage (about 2%) of the beam power while reflecting the rest. The picked-off beam is detected by a quadrature detector, and the information is displayed by a power meter. The system allows the use of two Smart Mirrors at different points in the optical path to provide power ratio and difference measurements.
