  2. LTspice - Wikipedia

    en.wikipedia.org/wiki/LTspice

    The text that describes intrinsic SPICE models can be placed directly on an LTspice schematic by using the spice directive .op button. [18] The advantage of this method is the 3rd party model is self-contained as part of the schematic when you distribute the schematic file.

  3. Polynomial texture mapping - Wikipedia

    en.wikipedia.org/wiki/Polynomial_texture_mapping

    Polynomial texture mapping (PTM), also known as Reflectance Transformation Imaging (RTI), is a technique of imaging and interactively displaying objects under varying lighting conditions to reveal surface phenomena. The data acquisition method is Single Camera Multi Light (SCML). [1]

  4. 1PN58 - Wikipedia

    en.wikipedia.org/wiki/1PN58

    [1] The light intensifier is powered by a pack of 5 D-0,55S (Russian: Д-0,55С) rechargeable cells, providing up to 7 V. The scope requires 6.25 V. The current drawn is 7 mA. The D-0,55S battery pack is used by a range of devices including 1PN51 and 1PN51-2 and has a separate charging device. The charging device has a switch to select one of ...

    en.wikipedia.org/wiki/Circuit_diagram

    A circuit diagram (or: wiring diagram, electrical diagram, elementary diagram, electronic schematic) is a graphical representation of an electrical circuit. A pictorial circuit diagram uses simple images of components, while a schematic diagram shows the components and interconnections of the circuit using standardized symbolic representations ...

    The ZG 1229 Vampir weighed 2.26 kilograms (5.0 lb) and was fitted with lugs on the StG 44 at C.G. Haenel in Suhl, the weapons production facility.As well as the sight and infrared spotlight, there was a wooden-cased battery for the light weighing 13.59 kilograms (30.0 lb), and a second battery fitted inside a gas mask container to power the image converter.

  7. Thermography - Wikipedia

    en.wikipedia.org/wiki/Thermography

    Some infrared cameras marketed as night vision are sensitive to near-infrared just beyond the visual spectrum, and can see emitted or reflected near-infrared in complete visual darkness. However, these are not usually used for thermography due to the high equivalent black-body temperature required, but are instead used with active near-IR ...

  8. Gaussian blur - Wikipedia

    en.wikipedia.org/wiki/Gaussian_blur

    In two dimensions, it is the product of two such Gaussian functions, one in each dimension: [1] [2] [3] (,) = + where x is the distance from the origin in the horizontal axis, y is the distance from the origin in the vertical axis, and σ is the standard deviation of the Gaussian distribution. It is important to note that the origin on these ...
