Path length control for laser angular rate sensors. |
摘要 |
<p>Electro-optical apparatus for the control of the optical path length in a laser angular rate sensor. An output of a fringe detector dual photodiode and preamplifier, normally present, is processed to recover a laser intensity component present as an amplitude modulation superimposed on the phase-modulated fringe detector signal. The laser intensity component is then provided as an input to the optical path length feedback control system.</p> |
