  2. Telecentric lens - Wikipedia

    en.wikipedia.org/wiki/Telecentric_lens

    An image-space telecentric lens has the exit pupil (the image of the aperture stop formed by optics after it) at infinity and produces images of the same size regardless of the distance between the lens and the film or image sensor. This allows the lens to focus light from an object or sample to different distances without changing the size of ...

    Image title Comparison of a conventional lens (1), object-space telecentric lens (2), image-space telecentric lens (3) and bi-telecentric lens (4), assuming the images are in sufficient focus by CMG Lee.

  4. Four Thirds system - Wikipedia

    en.wikipedia.org/wiki/Four_Thirds_system

    A telecentric lens design can mitigate this problem, but the sensor remains more sensitive to the angle of incoming light, and has more pronounced image corner light falloff. The resolution of a sensor is often measured as the total sensor pixel count in megapixels, and this is often a primary decision-making factor in choosing a camera ...

  5. Optical resolution - Wikipedia

    en.wikipedia.org/wiki/Optical_resolution

    The ability of a lens to resolve detail is usually determined by the quality of the lens, but is ultimately limited by diffraction.Light coming from a point source in the object diffracts through the lens aperture such that it forms a diffraction pattern in the image, which has a central spot and surrounding bright rings, separated by dark nulls; this pattern is known as an Airy pattern, and ...

    Telecentric lens. Compound lens with an unusual property concerning its geometry of image-forming rays. In machine vision systems telecentric lenses are usually employed in order to achieve dimensional and geometric invariance of images within a range of different distances from the lens and across the whole field of view. Telephoto lens. Lens ...

  8. Lytro - Wikipedia

    en.wikipedia.org/wiki/Lytro

    The Lytro ILLUM features a 40 megaray sensor (in comparison to the original Lytro Camera's 11 megaray sensor), and a more powerful processor. The 30-250mm lens has 8.3x optical zoom, an f/2.0 aperture, and 1:3 macro focus capability. The lens was designed to weigh half a pound to make the camera lighter and more agile.

  9. Multi-exposure HDR capture - Wikipedia

    en.wikipedia.org/wiki/Multi-exposure_HDR_capture

    Tone mapped high-dynamic-range (HDR) image of St. Kentigern's Church in Blackpool, Lancashire, England. In photography and videography, multi-exposure HDR capture is a technique that creates high dynamic range (HDR) images (or extended dynamic range images) by taking and combining multiple exposures of the same subject matter at different exposures.
