SpletLine spread function and edge response. The line spread function (LSF) is the derivative of the edge response. The width of the LSF is usually expressed as the Full-Width-at-Half … The line spread function can be found using two different methods. It can be found directly from an ideal line approximation provided by a slit test target or it can be derived from the edge spread function, discussed in the next sub section. Edge-spread function Prikaži več The optical transfer function (OTF) of an optical system such as a camera, microscope, human eye, or projector specifies how different spatial frequencies are captured or transmitted. It is used by optical engineers … Prikaži več Although one typically thinks of an image as planar, or two-dimensional, the imaging system will produce a three-dimensional intensity … Prikaži več The optical transfer function is not only useful for the design of optical system, it is also valuable to characterize manufactured … Prikaži več Since the optical transfer function (OTF) is defined as the Fourier transform of the point-spread function (PSF), it is generally speaking a Prikaži več The OTF of an ideal lens system A perfect lens system will provide a high contrast projection without shifting the periodic pattern, … Prikaži več Most optical design software has functionality to compute the optical or modulation transfer function of a lens design. Ideal systems such as in the examples here are … Prikaži več In practice, many factors result in considerable blurring of a reproduced image, such that patterns with spatial frequency just … Prikaži več
