Lateral chromatic aberration (CA) of color cameras has great effects on the imaging quality. This paper presents a novel method to full-field calibrate lateral CA between color channels by using unwrapped phase data. Closed circle sinusoidal fringe patterns having the optimum three-fringe numbers are generated and displayed on a liquid crystal screen consecutively through red, green and blue ch...

In this paper, we present several applications of the Michelson Interferometer in analyzing monochromatic, dichromatic, and white light. First, the wavelength of the mercury green line is determined to be 540 ± 36theo ± 10sys nm by measuring the fringe separation. An estimate was made by counting fringes passing a reference point as a platform mounted mirror was moved translationally with a pre...

We present a new method using Bayesian probability theory and neural networks for the evaluation of speckle interference patterns for an automated analysis of deformation and erosion measurements. The method is applied to the fringe pattern reconstruction of speckle measurements with a Twyman-Green interferometer. Given a binary speckle image, the method returns the fringe pattern without noise...

By adding the energy produced in the interferograms and absorbed by the interferometer itself, it must be possible to prove energy conservation in any interferometer. This calculation is relatively simple for two port interferometers such as the Twyman-Green and Mach-Zehnder. If nonabsorbing beam splitters are used, primary and complementary fringe patterns are produced such that when a dark fr...

The refractive index of a lens varies for different wavelengths of light, and thus the same incident light with different wavelengths has different outgoing light. This characteristic of lenses causes images captured by a color camera to display chromatic aberration (CA), which seriously reduces image quality. Based on an analysis of the distribution of CA, a full-field calibration method based...

Abstract Inspired by empirical evidence from the oil market, we build a model of an oligopoly facing fringe as well competition renewable resources. We explore different subclasses HARA utility functions (Cobb–Douglas, power and quadratic utility) to check robustness results found in previous literature. For isoelastic demand, characterize equilibrium extraction rates oligopolists. There always...

The MIT Mark IV holographic display system employs a novel anisotropic leaky-mode spatial light modulator that allows for the simultaneous and superimposed modulation of red, green, and blue light via wavelength-division multiplexing. This WDM-based scheme for full-color display requires that incoming video signals containing holographic fringe information are comprised of non-overlapping spect...

The H20 line emission (rest frequency equal to 22235. 08 MHz) regions in W49 and Orion A were measured during June 1970, at three radio astronomical receiving stations: the 120 ft antenna of the Haystack Observatory in Tyngsboro, Massachusetts, and the 140 ft and 36 ft antennas of the National Radio Astronomy Observatory at Green Bank, West Virginia, and Kitt Peak, Arizona. The Haystack-Green B...
