  2. Optical transfer function - Wikipedia

    en.wikipedia.org/wiki/Optical_transfer_function

    The image of a point source is also a three dimensional (3D) intensity distribution which can be represented by a 3D point-spread function. As an example, the figure on the right shows the 3D point-spread function in object space of a wide-field microscope (a) alongside that of a confocal microscope (c).

  3. Confocal microscopy - Wikipedia

    en.wikipedia.org/wiki/Confocal_microscopy

    Fluorescence and confocal microscopes operating principle. Confocal microscopy, most frequently confocal laser scanning microscopy (CLSM) or laser scanning confocal microscopy (LSCM), is an optical imaging technique for increasing optical resolution and contrast of a micrograph by means of using a spatial pinhole to block out-of-focus light in image formation. [1]

  4. Point spread function - Wikipedia

    en.wikipedia.org/wiki/Point_spread_function

    The degree of spreading (blurring) in the image of a point object for an imaging system is a measure of the quality of the imaging system. In non-coherent imaging systems, such as fluorescent microscopes, telescopes or optical microscopes, the image formation process is linear in the image intensity and described by a linear system theory. This ...

  5. Microscopy - Wikipedia

    en.wikipedia.org/wiki/Microscopy

    The single lens with its attachments, or the system of lenses and imaging equipment, along with the appropriate lighting equipment, sample stage, and support, makes up the basic light microscope. The most recent development is the digital microscope, which uses a CCD camera to focus on the exhibit of interest. The image is shown on a computer ...

  6. Diffraction-limited system - Wikipedia

    en.wikipedia.org/wiki/Diffraction-limited_system

    In a digital camera, diffraction effects interact with the effects of the regular pixel grid. The combined effect of the different parts of an optical system is determined by the convolution of the point spread functions (PSF). The point spread function of a diffraction limited circular-aperture lens is simply the Airy disk. The point spread ...

  7. Microscope image processing - Wikipedia

    en.wikipedia.org/wiki/Microscope_image_processing

    Microscope image processing is a broad term that covers the use of digital image processing techniques to process, analyze and present images obtained from a microscope. Such processing is now commonplace in a number of diverse fields such as medicine , biological research , cancer research , drug testing , metallurgy , etc.

  8. Laser scanning - Wikipedia

    en.wikipedia.org/wiki/Laser_scanning

    Laser scanning is the controlled deflection of laser beams, visible or invisible. [1] Scanned laser beams are used in some 3-D printers, in rapid prototyping, in machines for material processing, in laser engraving machines, in ophthalmological laser systems for the treatment of presbyopia, in confocal microscopy, in laser printers, in laser shows, in Laser TV, and in barcode scanners.

  9. Andor Technology - Wikipedia

    en.wikipedia.org/wiki/Andor_Technology

    The microscope is designed to be simple to use and is based around a Spinning Disk Confocal approach. It incorporates an sCMOS camera and a 4-line laser engine. In August 2022, Andor’s benchtop confocal microscope (BC43) won Microscopy Today Innovation Award, run by the American top-tier publication Microscopy Today. [29]
