Zhuo Yongmu, Yang Yongying(Optical Instrument Department, Zhejiang University)
A laser angle measuring system for attach angle measurement of modelplane in supersonic wind-tunnel is described in the paper.The system consistsof angle measurement, track and compensation. The principles of the threeparts and initial experiments are presented. The angle measuring accuracy is0.005°,angle measuring speed is 120°/s, and the range of angle measurementis±20°.
