Fringe counting interferometer
WebFundamentals of Interferometry 1 Two-Beam Interference Equation Interferometric optical testing is based on the phenom-ena of interference. Two-beam interference is the super-position of two waves, such as the disturbance of the sur-face of a pond by a small rock encountering a similar pat-tern from a second rock. When two wave crests reach the Webtechnical report: fringe-counting readout system for a length-measuring laser interferometerfringe-counting readout system for a length-measuring laser interferometer

WebNov 3, 2024 · Laser interferometers allow producing fringe patterns without requiring that the surfaces be close together. That is a consequence of the relatively long coherence length of most lasers. ... Fringe Pattern Conversion to Waves. When multiple circular fringes are detected, counting from a null fringe to the furthest outlying fringe yields double ... WebApr 12, 2024 · Testing of the proposed interferometer should focus on its resolution, as the operation of similar interferometers in the fringe counting mode is already well-researched. This requires a means of introducing small amounts of phase difference or optical path length difference into the light incident on the Wollaston prism.
WebLaser interferometry [1] that is based on fringe counting has high resolution and stability of measurement. However, its precision and stability are depended on the wavelength of light. ...
