为了解决激光模拟射击中由于图像畸变和光斑中心定位误差而造成命中环数计算结果与实际值偏差较大的问题,提出一种高精度命中环数算法。算法通过参考点确定靶环中心,采用带阈值处理的灰度重心法计算光斑中心,利用参考点对畸变图像进行透视变形校正和径向畸变校正,消除因图像畸变而带来的计算误差,最后计算出准确的射击命中环数。实验结果表明,高精度命中环数算法能有效消除误差,提高命中环数计算精度,命中环数达到01环级别,光斑中心在靶面上的定位精度达到01mm级,满足激光模拟射击技术要求,在激光模拟射击中具有实用意义。 相似文献

A multidimensional semiconductor laser simulator is presented which follows a rate equation approach for the coupling between optics and electronics. Capture and emission rates for the bound and free carriers are used for the quantum well. The electronic equations and the optical equations are solved in a self-consistent manner for one, two, and three dimensions. As an example, an InGaAs quantum-well ridge laser is analyzed, and the multidimensional simulation approach for Fabry-Perot device structures is discussed. A three-dimensional (3-D) simulation of a device with a truncated contact shows the applicability of the simulator to complex laser cavity designs 相似文献

We describe a laboratory-scale 109 nm Xe Auger laser pumped by an all-commercial high-repetition-rate Nd:YAG laser system. The Xe laser provides pulse energies up to 1 μJ, and an average flux of 3×10 12 photons/s at 11.5 eV. Measurements of the gain, output energy, and output beam shape are reported, along with an investigation of the time dependence of the gain 相似文献

A two-dimensional device simulator for designing laser diodes has been developed. The wave equation and the rate equation for photons, as well as Poisson's equation and the current-continuity equations for electrons and holes, are solved numerically. The letter can reveal precisely the operation mechanism of laser diodes. 相似文献
