    en.wikipedia.org/wiki/Shack–Hartmann_wavefront...

    A Shack–Hartmann (or Hartmann–Shack) wavefront sensor (SHWFS) is an optical instrument used for characterizing an imaging system. [1] [2] It is a wavefront sensor commonly used in adaptive optics systems. It consists of an array of lenses (called lenslets) of the same focal length.

    en.wikipedia.org/wiki/Adaptive_optics

    The wavefront of an aberrated image (left) can be measured using a wavefront sensor (center) and then corrected for using a deformable mirror (right). Adaptive optics ( AO ) is a technique of precisely deforming a mirror in order to compensate for light distortion.

    en.wikipedia.org/wiki/White_light_interferometry

    Figure 2: Optical setup of a Twyman-Green interferometer with a CCD image sensor. The interference occurs for white light when the path lengths of the measurement beam and the reference beam are nearly matched. By scanning (changing) the measurement beam path length relative to the reference beam, a correlogram is generated at each pixel. The ...

    From 2005 to 2009, Optica Software was sold by iCyt Mission Technology Inc, Champaign, Illinois (renamed Sony Biotechnology Inc in 2010). At iCyt, Optica2 was renamed as Rayica, and Wavica and LensLab were also developed. Later Rayica-Wavica was combined and named back to Optica3.

  8. Wavefront - Wikipedia

    en.wikipedia.org/wiki/Wavefront

    A wavefront sensor is a device which measures the wavefront aberration in a coherent signal to describe the optical quality or lack thereof in an optical system. There are many applications that include adaptive optics , optical metrology and even the measurement of the aberrations in the eye itself.
