generate double - beam interference，is introduced according to the optical wave theory. The
formulae of optical path difference and phase difference have been derived; the
interference conditions and distribution laws of spots or fringes are also quantitatively
analyzed in detail. Its possible application and supplement function in teaching and researching
activ- ities are also discussed.
