Paper Abstract

The drift performance of an optical rotation sensor employing a passive ring cavity is presented. With a square cavity of about 17 cm on a side, and a 1 mW external laser, the rms fluctuation in the measurement of rotation was 0.45°/hour for an integration time of 1 second. This is consistent with the shot-noise-limited performance expected for the present setup.
