Optical correlator — An optical correlator is a device for comparing two signals by utilising the Fourier transforming properties of a lens.[1] It is commonly used in optics for target tracking and identification. Contents 1 Introduction 2 Implementation … Wikipedia
Fourier optics — is the study of classical optics using techniques involving Fourier transforms and can be seen as an extension of the Huygens Fresnel principle. The underlying theorem that light waves can be described as made up of sinusoidal waves, in a manner… … Wikipedia
Coherence (physics) — In physics, coherence is a property of waves that enables stationary (i.e. temporally and spatially constant) interference. More generally, coherence describes all properties of the correlation between physical quantities of a wave. When… … Wikipedia
Holography — (from the Greek, ὅλος hólos whole + γραφή grafē writing, drawing) is a technique that allows the light scattered from an object to be recorded and later reconstructed so that it appears as if the object is in the same position relative to the… … Wikipedia

Displacement operator — Quantum optics operators Ladder operators Creation and annihilation operators Displacement operator Rotation operator (quantum mechanics) Squeeze operator Anti symmetric operator Quantum corre … Wikipedia
radar signal film — The film on which is recorded all the reflected signals acquired by a coherent radar, and that must be viewed or processed through an optical correlator to permit interpretation … Military dictionary
Interferometry — is the technique of using the pattern of interference created by the superposition of two or more waves to diagnose the properties of the aforementioned waves. The instrument used to interfere the waves together is called an interferometer.… … Wikipedia
