Optische transmission
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 in image space that in principle can be … 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 the Nyquist rate may not even be visible, … 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 The optical transfer function is not only useful for the design of optical system, it is also valuable to characterize manufactured … 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 … See more Webtransmission at high speed, an experiment was conducted at 10-Gb/s capacity per wavelength. Four 2.5-Gb/s digital signals were mixed with four RF carriers each at 3.6, 8.3, 13, and 18 GHz, and binary phase-shift keying (BPSK) modulation format was used in the RF domain. The RF carriers were then combined and amplified to drive a dual electrode ...
