| Abstract: | A laser measuring system for initial disturbances of rockets was developed based on "optical lever" principle. The composition and basic principle of the system are introduced briefly. In the system, the wavelength of semiconductor lusing light e-mitter is 650 nm,the resolution of the position sensitive detector (PSD) is 10~(-6) m and the measuring error is less than 2 × 10~(-5)rad.A measuring experiment was carried out with 54 mm rocket using this system. The comparison with the simulation results show that the experimental results are rational and credible. Finally, an error analysis was made for the system. |
