High Speed Infrared Sensor for Jitter Correction

For laser tracking applications, a sensor with a high frame rate and sensitivity to infrared wavelengths is required. Aerius proposes to make a 256x256 sensor with a frame rate of 10 kHz. The sensor will include a detector array made from InGaAs so that it is sensitive to wavelengths from 800 nm 1700 nm. The full receiver (sensor and interface electronics) will provide location and amplitude data on the laser beam of interest. Aerius"proposed sensor is also scalable to 512x512 in future versions but still using the same core developed for the 256x256. This 512x512 sensor would also have a frame rate of 10 kHz, but it would only output the data of interest rather than the whole array. The receiver developed during Phase II will provide location data to the control system in order to control the steering mirrors. In Phase I, Aerius will demonstrate high frame rates on a 128x128 sensor.
