摘要
通过严密的数学推导,得出实现干涉需要三个条件:频率相同,振动方向相同和相位差恒定,具体的方法为分波面法与分振幅法;同时还需要满足两个附加条件:两束相干光的振幅不能相差太大和其光程差不能太大。
Through the reduction by mathematical method,The realization of interference needs the following three condition：the same frequency, the same vibrating direction and the constant phase difference,and the concrete methods are divided into the interference between divided wave surfaces and the interference between divided amplitudes;at the same time,the following two additional conditions should be met： the amplitudes of the two coherent lights can＇t differ too much and the optical path difference between them can＇t be too big.
