摘要
A novel precise angle gauge is proposed. Incoming laser light is fed to the system through two separate condensing lenses. The phase difference between two rays are compensated by a phase modulator to hold a constant interference condition. The angle of the incoming light is measured by the modulation voltage. In comparison with conventional angle gauges, its advantages are: 1) high measurement accuracy, 2) simple structure, and 3) compatibility to feedback control systems. Owing to these advantages, the angle gauge is suitable for navigation using angular information. © 1990 IEEE
