optical readout
1Optical 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… …
23D optical data storage — is the term given to any form of optical data storage in which information can be recorded and/or read with three dimensional resolution (as opposed to the two dimensional resolution afforded, for example, by CD). [ Three Dimensional Optical Data …

4NV-центр — (англ. nitrogen vacancy center) или азото замещённая вакансия в алмазе  это один из многочисленных точечных дефектов алмаза. Дефект представляет собой нарушение строения кристаллической решётки алмаза, возникающий при удалении атома… …
5Nanopore sequencing — is a method under development since 1995 [1][2] for determining the order in which nucleotides occur on a strand of DNA. A nanopore is simply a small hole, of the order of 1 nanometer in internal diameter. Certain transmembrane cellular proteins… …
6Active pixel sensor — An active pixel sensor (APS) is an image sensor consisting of an integrated circuit containing an array of pixel sensors, each pixel containing a photodetector and an active amplifier. There are many types of active pixel sensors including the… …
7Holographic data storage — is a potential replacement technology in the area of high capacity data storage currently dominated by magnetic and conventional optical data storage. Magnetic and optical data storage devices rely on individual bits being stored as distinct… …
8Laser beam profiler — A laser beam profiler captures, displays, and records the spatial intensity profile of a laser beam at a particular plane transverse to the beam propagation path. Since there are many types of lasers ultraviolet, visible, infrared, continuous… …
9Charge-coupled device — A specially developed CCD used for ultraviolet imaging in a wire bonded package. A charge coupled device (CCD) is a device for the movement of electrical charge, usually from within the device to an area where the charge can be manipulated, for… …
10Flow measurement — is the quantification of bulk fluid movement. Flow can be measured in a variety of ways. Positive displacement flow meters acumulate a fixed volume of fluid and then count the number of times the volume is filled to measure flow. Other flow… …
