  2. Point spread function - Wikipedia

    en.wikipedia.org/wiki/Point_spread_function

    The point spread function (PSF) describes the response of a focused optical imaging system to a point source or point object. A more general term for the PSF is the system's impulse response; the PSF is the impulse response or impulse response function (IRF) of a focused optical imaging system. The PSF in many contexts can be thought of as the ...

  3. Optical transfer function - Wikipedia

    en.wikipedia.org/wiki/Optical_transfer_function

    Formally, the optical transfer function is defined as the Fourier transform of the point spread function (PSF, that is, the impulse response of the optics, the image of a point source). As a Fourier transform, the OTF is generally complex-valued; however, it is real-valued in the common case of a PSF that is symmetric about its center.

  4. Progressive segmented frame - Wikipedia

    en.wikipedia.org/wiki/Progressive_segmented_frame

    Progressive segmented Frame (PsF, sF, SF) is a scheme designed to acquire, store, modify, and distribute progressive scan video using interlaced equipment.. With PsF, a progressive frame is divided into two segments, with the odd lines in one segment and the even lines in the other segment.

  5. PSF Lab - Wikipedia

    en.wikipedia.org/wiki/PSF_Lab

    PSF Lab is a software program that allows the calculation of the illumination point spread function (PSF) of a confocal microscope under various imaging conditions. The calculation of the electric field vectors is based on a rigorous, vectorial model that takes polarization effects in the near-focus region and high numerical aperture microscope objectives into account.

    The Palestinian Preventive Security (PPS; Arabic: الأمن الوقائي, romanized: Al-’amn al-wiqā’ī), also known as Preventive Security Force (PSF), Preventive Security Service (PSS), is one of the security organs of the State of Palestine. It was established in 1994 by president Yasser Arafat in accordance with the Oslo Accords.

  8. HDCAM - Wikipedia

    en.wikipedia.org/wiki/HDCAM

    HDCAM deck HDCAM L tape. SMPTE 367M, also known as SMPTE D-11, is the SMPTE standard for HDCAM. The standard specifies compression of high-definition digital video. D11 source picture rates can be 24, 24/1.001, 25 or 30/1.001 frames per second progressive scan, or 50 or 60/1.001 fields per second interlaced; compression yields output bit rates ranging from 112 to 140 Mbit/s.
