【Abstract】 The bubble has dividing wave front functions in the optically denser medium.When a parallel laser beam is irradiating the bubble,circular interference fringes are produced in the distant field.After this,a formula on optical path length difference is derived.The characteristics of interference fringe are analysed and its application prospects are expected.更多还原
