Abstract
In support of the development of a new initiative in the field of multiplexed image spectroscopy, a high torque, servo system was developed. Utilizing only a low resolution shaft position encoder, the system demonstrated an excellent ability to track a pulse input signal with high precision and stability. Ultimately, this servo system will be incorporated into a new generation of multiplexed imaging and imaging spectroscopy instruments. It will provide those instruments with the capability to accurately rotate into position a sequence of optical image encoding masks and it will tightly control that position, even in the presence of external perturbations. A computer will read the light intensity signals from a sensor and quickly decode the image for viewing and analysis. Further research into this technology should lead to full development of an extremely efficient infrared imaging system, with additional applications to passive surveillance, target signature identification, and airborne infrared astrophysics.
