Optics distortion

WebMicroscopes and other optical instruments are commonly plagued by lens errors that distort the image by a variety of mechanisms associated with defects (commonly referred to as aberrations) resulting from the spherical geometry of lens surfaces. There are three primary sources of non-ideal lens action (errors) that are observed in the microscope. WebApr 12, 2024 · The distortion correction is the key step for accurate coordinate system transformation. Two types of distortions exist when imaging a tube-like specimen by OCT. One is the distortion induced by the difference between the lateral and axial resolutions, the other is the distortion induced by the curved surface and the changes of the refractive ...

WebWe present a fast and flexible non-interferometric method for the correction of small surface deviations on spatial light modulators, based on the Gerchberg-Saxton algorithm. The surface distortion information is extracted from the shape of a single optical vortex, which is created by the light modulator. The method can be implemented in optical tweezers … WebWhile "distortion" can include arbitrary deformation of an image, the most pronounced modes of distortion produced by conventional imaging optics is "barrel distortion", in which the center of the image is magnified more than the perimeter (figure 3a). WebDistortion in a simple lens is a third-order aberration which increases with the cube of the field height.
