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 pattern is represented by a complex number with absolute value and complex argument … See more 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 … See more Although one typically thinks of an image as planar, or two-dimensional, the imaging system will produce a three-dimensional intensity distribution … See more 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 readily calculated numerically using software such as Julia, GNU Octave 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, hence the optical transfer function is identical … See more The optical transfer function is not only useful for the design of optical system, it is also valuable to characterize manufactured … See more In practice, many factors result in considerable blurring of a reproduced image, such that patterns with spatial frequency just below the Nyquist rate may not even be visible, … See more WebHF-12M series. For Company D that needs to prevent a decline in inspection accuracy because of optical axis shift of lens, Fujifilm’s unique shock-resistant and anti-vibration functions is a reliable solution, which appeals to customers. Company D introduced the “HF-12M” lens series with shock-resistant and anti-vibration functions.
