2. Distortion (optics) - Wikipedia

   en.wikipedia.org/wiki/Distortion_(optics)

   The Micro Four Thirds system cameras and lenses perform automatic distortion correction using correction parameters that are stored in each lens's firmware, and are applied automatically by the camera and raw converter software. The optics of most of these lenses feature substantially more distortion than their counterparts in systems that do ...

3. Prism (optics) - Wikipedia

   en.wikipedia.org/wiki/Prism_(optics)

   Prism spectacles with a single prism perform a relative displacement of the two eyes, thereby correcting eso-, exo, hyper- or hypotropia. In contrast, spectacles with prisms of equal power for both eyes, called yoked prisms (also: conjugate prisms, ambient lenses or performance glasses) shift the visual field of both eyes to the same extent. [5]

4. Prism cover test - Wikipedia

   en.wikipedia.org/wiki/Prism_Cover_Test

   The prism cover test (PCT) is an objective measurement and the gold standard in measuring strabismus, i.e. ocular misalignment, or a deviation of the eye. [1] It is used by ophthalmologists and orthoptists in order to measure the vertical and horizontal deviation and includes both manifest and latent components. [1]

5. Achromatic lens - Wikipedia

   en.wikipedia.org/wiki/Achromatic_lens

   Several different types of achromat have been devised. They differ in the shape of the included lens elements as well as in the optical properties of their glass (most notably in their optical dispersion or Abbe number).

6. Chromatic aberration - Wikipedia

   en.wikipedia.org/wiki/Chromatic_aberration

   Detailed knowledge of the optical system used to produce the image can allow for some useful correction. [15] In an ideal situation, post-processing to remove or correct lateral chromatic aberration would involve scaling the fringed color channels, or subtracting some of a scaled versions of the fringed channels, so that all channels spatially ...

7. Bayer filter - Wikipedia

   en.wikipedia.org/wiki/Bayer_filter

   In professional cameras, image correction functions are completely absent, or they can be turned off. Recording in Raw-format provides the ability to manually select demosaicing algorithm and control the transformation parameters, which is used not only in consumer photography but also in solving various technical and photometric problems.
