Weak gravitational lensing — While the presence of any mass bends the path of light passing near it, this effect rarely produces the giant arcs and multiple images associated with strong gravitational lensing. Most lines of sight in the universe are thoroughly in the weak… … Wikipedia
Time Reversal Signal Processing — is a technique for focusing waves. A Time Reversal Mirror (TRM) is a device that can focus waves using the time reversal method. TRMs are also known as time reversal mirror arrays, as they are usually arrays of transducers, but they do not have… … Wikipedia
Optical heterodyne detection — is an important special case of heterodyne detection. In heterodyne detection, a signal of interest at some frequency is non linearly mixed with a reference local oscillator (LO) that is set at a close by frequency. The desired outcome is the… … Wikipedia
Error detection and correction — In mathematics, computer science, telecommunication, and information theory, error detection and correction has great practical importance in maintaining data (information) integrity across noisy channels and less than reliable storage… … Wikipedia
Multiuser detection — (also known as joint detection) is one of the receiver design technology for detecting desired signal(s) from interference and noise. Traditionally single user receiver is known suffering from the so called near far problem, where a near by or… … Wikipedia
Homodyne detection — is a method of detecting frequency modulated radiation by non linear mixing with radiation of a reference frequency, the same principle as for heterodyne detection.In optical interferometry, homodyne signifies that the reference radiation (the… … Wikipedia
Coincidence detection in neurobiology — For the electronic device, see Coincidence circuit. Coincidence detection in the context of neurobiology is a process by which a neuron or a neural circuit can encode information by detecting the occurrence of timely simultaneous yet spatially… … Wikipedia
Atomic line filter — A potassium Faraday filter designed, built and photographed by Jonas Hedin for making daytime LIDAR measurements at Arecibo Observatory.[1] An atomic line filter (ALF) is an advanced optical band pass filter used in the physical sciences for… … Wikipedia

Spectrum analyzer — A spectrum analyzer Spectrum analyzer display A spectrum analyzer measures the magnitude of an input signal versus frequency with … Wikipedia
Receiver operating characteristic — In signal detection theory, a receiver operating characteristic (ROC), or simply ROC curve, is a graphical plot of the sensitivity vs. (1 specificity) for a binary classifier system as its discrimination threshold is varied. The ROC can also be… … Wikipedia
