WebMay 30, 2024 · For wedge shape air film, the locus of points of equal thickness is straight lines parallel to the edge of the wedge. So, fringes appear straight and parallel. What is a … WebA wedge is a triangular shaped tool, and is a portable inclined plane, and one of the six simple machines.It can be used to separate two objects or portions of an object, lift up an … The air-wedge shearing interferometer is probably the simplest type of interferometer designed to visualize the disturbance of the wavefront after propagation through a test object. This interferometer is based on utilizing a thin wedged air-gap between two optical glass surfaces and can be used with virtually any light … See more An air-wedge shearing interferometer is described in and was employed in set of experiments described in. This interferometer consists of two optical glass wedges (~2-5deg), pushed together and then slightly … See more To minimize image aberrations the angle plane of the glass wedges has to be placed orthogonal to the angle plane of the air-wedge. Because … See more The air-wedge shearing interferometer is similar to the classical shearing interferometer but is micrometres thick, can operate with … See more Because of its extremely thin air-gap, the air-wedge interferometer was successfully applied in experiments with femto-second high-power lasers. Figure 4 shows an interferogram of laser interactions with a He jet in a vacuum chamber.
