【摘要】 介绍一种新型的光学元件，它可把一束激光变换成一个两维的激光平面。本文用多光束干涉的原理解释了光平面形成的原理，同时对应用前景及实用情况也作了一些估计更多还原

【Abstract】 A new optical element called Glass Ring is introduced in this paper. It can transform laser beam into a laser beam plane. The mechanism of the laser beam plane forming is explained by the principle of multi light beams coherent interference. Some application and possible future applications of the glass ring are also introduced.更多还原
