Abstract:
A new rapid scan phase modulator has been studied in a range of interferometric applications from the visible to the millimeter wave region. The modulator consists of two parallel mirrors mounted on a rotating platform. It causes little attenuation and is capable of large changes in optical path length at high speeds. The system is relatively insensitive to vibration and can yield a nearly flat transmission envelope.
