补充资料:光波传播
光波传播 light wave propagation 可见光、红外线和紫外线在大气中的传播。光波在大气中传播时,受到大气的吸收、散射、折射和闪烁等影响,影响程度与光波波长有密切关系。红外线波长范围为0.70微米~1毫米,是介于无线电波和可见光之间的相当宽的重要波段。其中300微米~1毫米区域的波又称为亚毫米波,有时也被划入无线电波的范围。大气对红外辐射传输的影响,主要表现为吸收和散射。大气对红外辐射的吸收,主要是由大气中的水蒸气、二氧化碳和高层大气中的臭氧分子所造成。可见光波长范围为380~700纳米。地球大气对可见光是透明的,散射、折射和闪烁是可见光在大气传输中的重要现象,同时还须考虑色散和某些吸收。可见光的波长比较短,瑞利散射的作用变得很重要,而且蓝色光的瑞利散射比红光更为强烈,因而天空看起来经常是蔚蓝色的。紫外线波长范围为10~380纳米,大气对紫外线的吸收非常强烈,只对波长为300纳米以上的近紫外线才允许有一定程度的透过。对于300纳米以下的紫外线,大气几乎是完全不透明的。 |
