A Fresnel Biprism is a variation on the Young's Slits experiment. The Fresnel biprism consists of two thin prisms joint at their bases to form an isosceles triangle. A single wavefront impinges on both prisms; the left por-tion of the wavefront is refracted right while the right segment is refracted left. In the region of superposition ...

A Fresnel biprism is a glass prism with a very large angle. A 5 cm focal length convex lens focuses the laser light on the biprism. The laser beam enters the flat side and exits at the tip of the symmetric triangle with the beam split by the two halves of the prism, which are very nearly parallel. The exiting halves of the beam are refracted so ...

In Fresnel's biprism experiment a biprism is used to make the two coherent sources of light. Then the waves from these two virtual sources interfere on the screen to give a pattern of bright and dark fringes. The biprism is made by joining two identical thin prisms base to base (as shown in the figure below). The angles of prisms are very small.
