【摘要】 利用"光学杠杆"原理研制了火箭弹初始扰动激光测量系统。介绍了该系统的基本原理和构成,系统中所用半导体激光发射器激光波长650 nm,位置灵敏探测器(PSD)的分辨率为10-6m,角度测量误差小于2×10-5rad。利用该系统对54 mm火箭弹进行了实际测试,对实验结果与理论计算结果进行了对比,证明实验结果合理可信。最后对测量系统进行了误差分析。更多还原

【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 lasing light emitter is 650 nm,the resolution of the position sensitive detector(PSD) is 10-6 m and the measuring error is less than 2×10-5rad.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.更多还原
