SA Photonics and Stanford University are pleased to propose the development of an innovative, high accuracy sense and control system for wide field of view ball joint gimbal mirrors. The SA Photonics mirror angle sense system utilizes optical sensors to directly measure the mirror angular position. The optical sensor system has better than 100 nanoradian sensitivity at update rates greater than 100 kHz with virtually no loading to the scanning mirror. Stanford University has best in class expertise in flexible drive systems such as the Kevlar drives used on ball joint gimbals. SA Photonics control platform utilizes high performance digital signal processing to both enhance the sensing capability and to allow complex drives algorithms to compensate for the flexible drives. The optical sensing system is inherently immune to EMI/EMP issues and leverages the massive cost reduction in optics over the last 10 years due to the very high volume compact disk, digital camera, and telecom markets.
