What is the Rayleigh criterion used for?
Angular resolution
Thermal expansion
Electrical conductivity
Magnetic susceptibility
Answer
Angular resolution refers to the ability to distinguish between two closely spaced objects. The Rayleigh criterion is a measure of the minimum angular separation between two objects that can be resolved by an optical system. It states that two objects are just resolvable when the center of the diffraction pattern of one object is directly over the first minimum of the diffraction pattern of the other object.
