摘　　要：针对一种快轴半功率角为23°的商用蓝色单管半导体激光器,设计制作了由直径为1.8 mm的自聚焦透镜、直径2.5 mm的柱透镜以及体布拉格光栅组成的光学系统以产生线结构光.研究结果表明,该方案可以实现在距离系统5.5 m处束宽为0.48 mm、在5.5±0.5 m范围内束宽低于0.60 mm的线结构光输出,可为线结构光测量方案的选择提供新的思路.A gradient-index lens with a diameter of 1.8 mm,a cylindrical lens with a diameter of 2.5 mm and a volume Bragg grating are designed and fabricated as an optical system for a commercial blue singletube semiconductor laser with a fast axis full width at half maxima of 23°.The experimental results show that this scheme can achieve a beam width of 0.48 mm at a distance of 5.5 m from the system,and the beam width is less than 0.60 mm in 5.5±0.5 m nearly,which can provide a new solution for the selection of the measurement scheme of line structured light.
