In addition, it is because collimated laser beam is free of focusing problem that output image can be projected to curve surface.
另外由于准直的激光束不存在聚焦问题，输出的图像能够准确投影到曲面上。
As before, the laser package is hermetically sealed for reliable operation in adverse environments and the laser output is collimated using an internal lens system.
密封激光包在恶劣环境下可靠运行，激光输出采用内部透镜系统校准。
In contrast, the light from non-laser light sources cannot be collimated by optics as well.
相反，从非激光平行光源发出的光就不能被光学所瞄准。
Dynamic modulation of laser and laser bean, and offset to target reflection coefficient: laser bean is shaped and collimated to round and slender beam by using of the semiconductor laser.
激光器件及激光束的动态调制，目标反射系数补偿：采用半导体激光器，经过整形、准直成圆细光束。
