WebEasy setup for single-shot MTF and WFE measurements. The unique capability of Phasics' patented Quadri-Wave Lateral Shearing Interferometry (QWLSI) wavefront sensing technology allows the measurement of high numerical aperture beams without the need of any relay optics. This unique advantage simplifies the measurement setup. To properly define the modulation transfer function, it is necessary to first define two terms required to truly characterize image performance: resolution and contrast. See more Now that the components of the modulation transfer function (MTF), resolution and contrast/modulation, are defined, consider MTF itself. The MTF of a lens, as the name implies, is a measurement of its … See more In traditional system integration (and less crucial applications), the system's performance is roughly estimated using the principle of the … See more

Choosing the Correct Test Target Edmund Optics
WebThe resolution and performance of an optical microscope can be characterized by a quantity known as the modulation transfer function (MTF), which is a measurement of the microscope's ability to transfer contrast from the specimen to the intermediate image plane at a specific resolution. WebSampling generally causes the response of a digital imaging system to be locally shift-variant and not directly amenable to MTF analysis. However, this paper demonstrates that a meaningful system response can be calculated by averaging over an ensemble of point-source system inputs to yield an MTF which accounts for the combined effects of image … WebThe Modulation Transfer Function (MTF) is an important tool to quantify the overall imaging performance of a system. MTF is a function of spatial frequency (v), which is generally in … phone number in sign language
