Solid State Analogue of a Double Slit Interferometer

subject

description

In a conventional optical double slit interferometer Fig. 1a light emerges from a source at a point O’, passes through two slits A and B and forms an interference pattern at a point O. If the source provides monochromatic radiation the coherence between optical paths O’AO and O’BO is preserved at all reasonable scales. The intensity of the interference pattern at a given point O can be altered by changing the distance ∣O’AO∣ - ∣O’BO∣.
