    en.wikipedia.org/wiki/Cosmic_Background_Explorer

    The Cosmic Background Explorer (COBE / ˈ k oʊ b i / KOH-bee), also referred to as Explorer 66, was a NASA satellite dedicated to cosmology, which operated from 1989 to 1993.Its goals were to investigate the cosmic microwave background radiation (CMB or CMBR) of the universe and provide measurements that would help shape the understanding of the cosmos.

    Comparison of the Sloan survey at left consisting of around 4 million galaxies and quasars taken from 2000 to 2020 and the DESI survey at right consisting of around 7.5 million during its 7 first months starting in 2021 and expected to be completed by 2026 with 35 million.

  5. Hyperspectral imaging - Wikipedia

    en.wikipedia.org/wiki/Hyperspectral_imaging

    Since a spectrum is an important diagnostic, having a spectrum for each pixel allows more science cases to be addressed. In astronomy, this technique is commonly referred to as integral field spectroscopy , and examples of this technique include FLAMES [ 50 ] and SINFONI [ 51 ] on the Very Large Telescope , but also the Advanced CCD Imaging ...

  6. Spectral power distribution - Wikipedia

    en.wikipedia.org/wiki/Spectral_power_distribution

    Mathematically, for the spectral power distribution of a radiant exitance or irradiance one may write: =where M(λ) is the spectral irradiance (or exitance) of the light (SI units: W/m 2 = kg·m −1 ·s −3); Φ is the radiant flux of the source (SI unit: watt, W); A is the area over which the radiant flux is integrated (SI unit: square meter, m 2); and λ is the wavelength (SI unit: meter, m).

  7. Texture mapping - Wikipedia

    en.wikipedia.org/wiki/Texture_mapping

    A texture map [5] [6] is an image applied (mapped) to the surface of a shape or polygon. [7] This may be a bitmap image or a procedural texture . They may be stored in common image file formats , referenced by 3D model formats or material definitions , and assembled into resource bundles .

    After pairing the remote, you just follow the instructions on screen to finish the set up. Note: After going through the setup process, at first I couldn’t get the TV to recognize the Xumo.

  9. Angular spectrum method - Wikipedia

    en.wikipedia.org/wiki/Angular_spectrum_method

    The angular spectrum method is a technique for modeling the propagation of a wave field.This technique involves expanding a complex wave field into a summation of infinite number of plane waves of the same frequency and different directions.
