In deep-space optical communication systems, precise pointing and aiming of the laser
beam is essential to ensure the stability of the laser link. In this paper, an adaptive …

The pointing and tracking performance of laser beams in free space optical communication
(FSOC) systems and other precision laser systems is severely limited by beam jitter. This …

In recent experimental research on adaptive control of jitter in laser beams, sufficiently high
levels of high frequency sensor noise have produced high frequency spikes in the output …

ABSTRACT (maximum 200 words) Acquisition, Tracking and Pointing (ATP) of space and
airborne optical beams is becoming an important research topic as the requirements for the …

The objective of this research is to develop control methods to attenuate laser beam jitter
using a fast-steering mirror. Adaptive filter controllers using Filtered-X least mean square …

Laser satellite communication has become especially attractive in recent years. However,
because the laser beam is very narrow and there is a long distance between satellites, the …

For several future imaging and communications spacecraft, a challenging area of
technology development is the fine acquisition, tracking, and pointing (ATP) control of the …

MANY future space missions, laser communication systems, and imaging systems will
require optical beam jitter control in the nanoradian regime [1]. Jitter is the undesired …

This paper presents new results on adaptive control of jitter in laser beams. Experimental
results illustrate the capability of a recently developed method for variable-order adaptive …

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 …
