  2. Readout integrated circuit - Wikipedia

    en.wikipedia.org/wiki/Readout_integrated_circuit

    A readout integrated circuit (ROIC) is an integrated circuit (IC) specifically used for reading detectors of a particular type. They are compatible with different types of detectors such as infrared and ultraviolet. The primary purpose for ROICs is to accumulate the photocurrent from each pixel and then transfer the resultant signal onto output ...

  3. Infrared detector - Wikipedia

    en.wikipedia.org/wiki/Infrared_detector

    Incident IR photons can cause electronic excitations. In photoconductive detectors, the resistivity of the detector element is monitored. Photovoltaic detectors contain a p-n junction on which photoelectric current appears upon illumination. An infrared detector is hybridized by connecting it to a readout integrated circuit with indium bumps ...

    Each company that manufactures microbolometers has their own unique procedure for producing them and they even use a variety of different IR absorbing materials. In this example the bottom layer consists of a silicon substrate and a readout integrated circuit . Electrical contacts are deposited and then selectively etched away.

  5. T-MOS thermal sensor - Wikipedia

    en.wikipedia.org/wiki/T-MOS_thermal_sensor

    The human body emitted radiation falls in the mid-infrared range peaking around 12 μm, so one of the applications of thermal sensors is fever detection. TMOS high performance, in terms of high sensitivity and low power consumption, and low costs fabrication process make it a promising candidate to implement contactless thermometer.

  6. Photodetector - Wikipedia

    en.wikipedia.org/wiki/Photodetector

    HgCdTe infrared detectors. Detection occurs when an infrared photon of sufficient energy kicks an electron from the valence band to the conduction band. Such an electron is collected by a suitable external readout integrated circuits (ROIC) and transformed into an electric signal. LEDs which are reverse-biased to act as photodiodes.
