Abstract

We describe modern angle measuring systems based on monolithic optics and modern information theory. These systems have a large field of view, no moving parts, small size, low weight, and the lowest possible costs in high-volume applications. In addition, the accuracy and precision of these angle measuring systems can be on the order of arc seconds or micro radians. We describe these systems and their applications to six degree-of-freedom localization and angular velocity estimation.
