  2. Transition-edge sensor - Wikipedia

    en.wikipedia.org/wiki/Transition-edge_sensor

    Optical image of four tungsten transition-edge sensors for near-infrared single-photon detection. Image credit: NIST. A transition-edge sensor (TES) is a type of cryogenic energy sensor or cryogenic particle detector that exploits the strongly temperature-dependent resistance of the superconducting phase transition.

  5. Quantum well infrared photodetector - Wikipedia

    en.wikipedia.org/wiki/Quantum_well_infrared...

    A Quantum Well Infrared Photodetector (QWIP) is an infrared photodetector, which uses electronic intersubband transitions in quantum wells to absorb photons. In order to be used for infrared detection, the parameters of the quantum wells in the quantum well infrared photodetector are adjusted so that the energy difference between its first and ...

  6. SENT (protocol) - Wikipedia

    en.wikipedia.org/wiki/SENT_(protocol)

    The SAE J2716 SENT (Single Edge Nibble Transmission) protocol [1] is a point-to-point scheme for transmitting signal values from a sensor to a vehicle controller. It is intended to allow for transmission of high resolution data with a low system cost.

  7. Edge detection - Wikipedia

    en.wikipedia.org/wiki/Edge_detection

    As a pre-processing step to edge detection, a smoothing stage, typically Gaussian smoothing, is almost always applied (see also noise reduction). The edge detection methods that have been published mainly differ in the types of smoothing filters that are applied and the way the measures of edge strength are computed.

  8. Metal L-edge - Wikipedia

    en.wikipedia.org/wiki/Metal_L-edge

    Metal L-edge spectroscopy is a spectroscopic technique used to study the electronic structures of transition metal atoms and complexes. This method measures X-ray absorption caused by the excitation of a metal 2p electron to unfilled d orbitals (e.g. 3d for first-row transition metals), which creates a characteristic absorption peak called the ...

  9. Optical transfer function - Wikipedia

    en.wikipedia.org/wiki/Optical_transfer_function

    The area is defined to encompass the edge of the target image. As shown in the right hand figure, an operator defines a box area encompassing the edge of a knife-edge test target image back-illuminated by a black body. The box area is defined to be approximately 10% [citation needed] of the total frame area.
