Optics Software for Layout and Optimization (OSLO) is an optical design program originally developed at the University of Rochester in the 1970s. The first commercial version was produced in 1976 by Sinclair Optics. Since then, OSLO has been rewritten several times as computer technology has advanced.
Zemax is a software program used for designing and simulating optical systems. It is widely used in the field of optics and photonics for designing and analyzing the performance of lenses, cameras, telescopes, microscopes, and other optical systems. With the software, the behavior of light interacting with various optical components can be ...
Chart 1 is the basic version, which is the most familiar and widely used chart among all the charts. In this chart the grid consists of 0.5 cm squares (each for 1° visual field), which totally measures 10 cm X 10 cm size. Most commonly grid is in white color with black background. [3]
Some examples of Optica being used in simulations and illustrations include holography, [2] x-ray optics, spectrometers, [3] Cerenkov radiation, [4] microwave optics, nonlinear optics, scattering, [5] camera design, [6] extreme ultraviolet lithography simulations, [7] [8] telescope optics, [9] [10] laser design, ultrashort pulse lasers, [11 ...
A 1951 USAF resolution test chart is a microscopic optical resolution test device originally defined by the U.S. Air Force MIL-STD-150A standard of 1951. The design provides numerous small target shapes exhibiting a stepped assortment of precise spatial frequency specimens.
The first step of computing an eye pattern is normally to obtain the waveform being analyzed in a quantized form. This may be done by measuring an actual electrical system with an oscilloscope of sufficient bandwidth, or by creating synthetic data with a circuit simulator in order to evaluate the signal integrity of a proposed design.
Additional benefits of fibre optic sensing technology are that it is immune to electromagnetic interference, vibration and is safe for use in hazardous zones (the laser power falls below the levels that can cause ignition), thus making these sensors ideal for use in industrial sensing applications.
Optical flow or optic flow is the pattern of apparent motion of objects, surfaces, and edges in a visual scene caused by the relative motion between an observer and a scene. [ 1 ] [ 2 ] Optical flow can also be defined as the distribution of apparent velocities of movement of brightness pattern in an image.
