tracking, adaptive optics, and optical beam jitter control. The testbed is designed to provide an end-to-end beam control demonstration of HEL systems. An optical Inertial Reference Unit (IRU) is a key element for optical jitter control to provide an inertially stabilized reference laser. Since most of the optical jitter is due to its own. Optical beam jitter control Article (PDF Available) in Proceedings of SPIE - The International Society for Optical Engineering June with 96 Reads How we measure 'reads'. a communications system or a weapon. For example, a mm diameter beam with 1 mrad of jitter will result in roughly a fold decrease in the intensity of the beam at km, due to the jitter alone. This paper summarizes the development of the Optical Relay Mirror Lab – Laser Jitter Control (LJC) Testbed, which is located in the. loop closed and used by the adaptive control loop.

The primary focus of this research is to develop and implement control schemes for combined broadband and narrowband disturbances to optical beams. The laser beam jitter control testbed developed at the Naval Postgraduate School is used for Cited by:   Optical beam jitter control Optical beam jitter control Watkins, R. Joseph; Chen, Hong-Jen; Agrawal, Brij N. For several future imaging and communications spacecraft, a challenging area of technology development is the fine acquisition, tracking, and pointing (ATP) control of the spacecraft and its payload. For example, some spacecraft with .   The adaptive controller achieves both fast adaptation and true minimum variance steady state performance. The main innovation in this paper is frequency weighting in the adaptive control loop to emphasize the relative importance of jitter in particular bandwidths and mitigate the effects of high-frequency sensor by:

This paper we will focus on the control of optical beam jitter. A Laser Jitter Control (LJC) testbed has been constructed to test jitter algorithms. The testbed consists of two fast steering mirrors (FSM), three position sensing modules (PSM), one diode laser, and several beam splitters and mirrors, all on an isolated Newport optical bench.

Adaptive optics (AO) is a technology used to improve the performance of optical systems by reducing the effect of incoming wavefront distortions by deforming a mirror in order to compensate for the distortion. It is used in astronomical telescopes and laser communication systems to remove the effects of atmospheric distortion, in microscopy, optical fabrication and in retinal .
