摘要
光密介质中的气泡具有分波阵面的作用,用平行激光束照射气泡时在远场产生圆环状干涉条纹,推导了光程差公式,分析了干涉条纹的特点,预期了应用前景.
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.
