Fresnel`s Bi-prism


Fresnel’s Bi-Prism is an optical device that produces two coherent sources from a single light source, leading to an interference pattern similar to Young’s Double-Slit Experiment. It consists of a thin bi-prism (two prisms joined at their bases), which creates two virtual sources of light.
