基于对红光激光束大气传输特性的分析，讨论了激光束传输过程中背景光干扰、大气衰减和湍流效应的影响。
Based on analysis on transmission property of red laser beam, impact from background light, attenuation and scintillation are discussed.
拿激光传输来说，卡拉里斯就称：“大量能量聚集成一束狭窄的激光束，可能会给人造成严重伤害。”
Take laser transmission, for example. "High powers concentrated in a narrow laser beam could cause serious damage to a person, " says Karalis.
Powerbeam公司的方案是为接收设备配备一枚小型荧光灯泡，这样传输器的摄像头就能跟踪光线，并适时引导激光束方向。
Powerbeam's solution is to fit a small fluorescent bulb to the receiving device so that a camera on the transmitter can track the light and steer the laser beam accordingly.
