WebPSF = otf2psf(OTF) computes the inverse Fast Fourier Transform of the optical transfer function (OTF) and creates a point-spread function (PSF), centered at the origin. PSF = … 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 to describe how the optics project light from the object or scene onto a photographic film, … See more Since the optical transfer function (OTF) is defined as the Fourier transform of the point-spread function (PSF), it is generally speaking a complex-valued function of spatial frequency. The projection of a specific periodic … See more Although one typically thinks of an image as planar, or two-dimensional, the imaging system will produce a three-dimensional intensity distribution in image space that in principle can be measured. e.g. a two-dimensional sensor could be translated to capture a three … See more The optical transfer function is not only useful for the design of optical system, it is also valuable to characterize manufactured systems. Starting from the point spread function The optical transfer function is defined as the See more Due to optical effects the contrast may be sub-optimal and approaches zero before the Nyquist frequency of the display is reached. The optical contrast reduction can be partially … See more The OTF of an ideal lens system A perfect lens system will provide a high contrast projection without shifting the periodic pattern, … See more Most optical design software has functionality to compute the optical or modulation transfer function of a lens design. Ideal … See more In practice, many factors result in considerable blurring of a reproduced image, such that patterns with spatial frequency just below … See more is shein in america
