摘要
激光散斑和激光光束一样 ,在散斑场的光强度比较大 ,观察距离又比较接近时 ,也可对活体眼造成损伤。本文根据光对人眼损伤的安全极限 ,导出了激光散斑在不引起视网膜光化学损伤、热损伤及角膜损伤时 ,扩束He-Ne激光的光斑直径、漫射板到观察者的距离与激光光功率之间的关系。
Like laser beam,laser speckle can also do damage to the eyes when it is intense and close to the eyes.With the help of the security limitation theory of light to eyes,we derive the relations among the speckle diameter of the He-Ne laser,the distance from diffusing screen to observer and laser power.
