paraxial focus 中文意思是什麼
paraxial focus
解釋
傍軸焦點-
To deal with the case of 2 dimension spatial self - focusing, it predicts the catastrophic collapse of a self - focusing beam in a kerr medium. this un - physical collapse is due to the invalidity of the paraxial wave equation in the neighborhood of a self - focus
在該理論應用於空間二維的自聚焦時,出現了光束將無限聚焦的結果,這在物理上是不可想像的,原因是在自聚焦點附近傍軸方程已經失效了。
