摘要
提出了一种基于内反射效应的二维微小角度传感器的设计方法。该传感器采用光学差动法,通过检测光强实现了对二维方向上微小角度的测量。研制的角度传感器俯仰角和偏转角的测量范围为±500arcsec;具有优于0.1arcsec的分辨力。
The design plan of 2D micro-angle sensor based on the effect of int ernal reflection was presented.The sensor employs optical differential method a nd achieved measurement of micro angle in 2D directions by detecting light inten sity.The measurement range of yaw angle and pitching angle of angle sensor deve loped are ±500 arcsec.The sensitivity of this sensor is betterthan 0.1 arcsec.
