Focus recovery based on the linear canonical transform — Focus recovery from defocused image is an ill posed problem since it loses the component of high freqency. Most of the methods for focus revocery are based on depth estimation theory [Most of depth recovery methods are simply based on camera… … Wikipedia
Optical sectioning — is the process by which a suitably designed microscope can produce clear images of a focal planes deep within a thick sample. This is used to reduce the need for thin sectioning using instruments such as the microtome. Many different techniques… … Wikipedia

Optical transfection — is the process of introducing nucleic acids into cells using light. Typically, a laser is focussed to a diffraction limited spot ( 1 µm diameter) using a high numerical aperture microscope objective. The plasma membrane of a cell is then… … Wikipedia
Optical lens design — refers to the calculation of lens construction parameters (variables) that will meet a set of performance requirements and constraints, including cost and schedule limitations. Construction parameters include surface profile types (spherical,… … Wikipedia
Focus — may refer to:In science, mathematics or computing: *Focus (optics), a point toward which light rays are made to converge **Autofocus, a feature of some optical systems that obtains and maintains correct focus on a target **Focal length, a measure … Wikipedia
