Holographic optical elements and charge coupled device technology at work in laser communications acquisition and tracking systems

摘要

In an effort to advance free space laser communication, Wright Laboratory's Laser Communications Laboratory personnel contracted the design and fabrication of a wide field-of-view holographic lens to image incoming laser radiation onto an electronic position-sensing device. The lens was fabricated to operate at a wavelength of 850 nm and mounted on a charge injection device (CID) camera. The author describes the lens and the hardware interface that combines the lens, camera, and MicroVAX computer into a wide field-of-view laser radiation angle-of-arrival sensor. He also provides a comparison of CID and charge coupled device (CCD) array technology with other position-sensing devices such as quad cells for use in future laser communications systems.
