  2. 1951 USAF resolution test chart - Wikipedia

    en.wikipedia.org/wiki/1951_USAF_resolution_test...

    A USAF 1951 resolution chart in PDF format is provided by Yoshihiko Takinami. This chart should be printed such that the side of the square of the 1st element of the group -2 should be 10 mm long. USAF 1951 Resolution Target Further explanations and examples; Koren 2003: Norman Koren's updated resolution chart better suited for computer analysis

  3. Optical resolution - Wikipedia

    en.wikipedia.org/wiki/Optical_resolution

    For example, a 2-megapixel camera of 20-micrometre-square pixels will have worse resolution than a 1-megapixel camera with 8-micrometre pixels, all else being equal. For resolution measurement, film manufacturers typically publish a plot of Response (%) vs. Spatial Frequency (cycles per millimeter). The plot is derived experimentally.

  4. Optical transfer function - Wikipedia

    en.wikipedia.org/wiki/Optical_transfer_function

    E.g. a microscope typically magnifies everything 10 to 100-fold, and a reflex camera will generally demagnify objects at a distance of 5 meter by a factor of 100 to 200. The resolution of a digital imaging device is not only limited by the optics, but also by the number of pixels, more in particular by their separation distance.

  5. Digital microscope - Wikipedia

    en.wikipedia.org/wiki/Digital_microscope

    A digital microscope is a variation of a traditional optical microscope that uses optics and a digital camera to output an image to a monitor, sometimes by means of software running on a computer. A digital microscope often has its own in-built LED light source, and differs from an optical microscope in that there is no provision to observe the ...

  6. Point spread function - Wikipedia

    en.wikipedia.org/wiki/Point_spread_function

    By virtue of the linearity property of optical non-coherent imaging systems, i.e., . Image(Object 1 + Object 2) = Image(Object 1) + Image(Object 2). the image of an object in a microscope or telescope as a non-coherent imaging system can be computed by expressing the object-plane field as a weighted sum of 2D impulse functions, and then expressing the image plane field as a weighted sum of the ...

  7. Image resolution - Wikipedia

    en.wikipedia.org/wiki/Image_resolution

    The time resolution used for movies is usually 24 to 48 frames per second (frames/s), whereas high-speed cameras may resolve 50 to 300 frames/s, or even more. The Heisenberg uncertainty principle describes the fundamental limit on the maximum spatial resolution of information about a particle's coordinates imposed by the measurement or ...

  8. Optical microscope - Wikipedia

    en.wikipedia.org/wiki/Optical_microscope

    The optical microscope, also referred to as a light microscope, is a type of microscope that commonly uses visible light and a system of lenses to generate magnified images of small objects. Optical microscopes are the oldest design of microscope and were possibly invented in their present compound form in the 17th century.

  9. USB microscope - Wikipedia

    en.wikipedia.org/wiki/USB_microscope

    The camera attaches directly to the USB port of a computer without the need for an eyepiece, and the images are shown directly on the computer's display. They usually provide modest magnifications (about 1× to 200×) without the need to use eyepieces, at cost very much lower than conventional stereomicroscopes . [ 1 ]
