| Abstract: | An optical interference apparatus with a regular triangle structure,which can 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 activities are also discussed. |
