<p>A readout device is provided for use in a ring laser angular rate sensor assembly which has improved low rate performance. Low rate performance is improved by reducing sources of backscatter thus not allowing light to be reflected back into the optical signal carrying medium. Backscatter is reduced by placing the optical sensors (62, 64) directly upon the gyro output mirror (14), thus causing the optical sensors to be dithered along with the laser block (10). By dithering the optical sensors, any backscatter caused by these elements is dealt with by dithering. While the optical sensors are dithered, the readout apparatus (44) continues to utilize the advantages of a case mounting.</p> |
