Diffraction effects in length measurements by laser interferometry.
High-accuracy dimensional measurements by laser interferometers require corrections because of diffraction, which makes the effective fringe-period different from the wavelength of a plane (or spherical) wave λ0. By using a combined X-ray and optical interferometer as a tool to investigate diffraction across a laser beam, we observed wavelength variations as large as 10-8λ...
متن کاملDiffraction Effects in Interferometry
Ping Zhou, James H. Burge College of Optical Science, University of Arizona, 1630 E. University Blvd., Tucson, AZ, USA 85721 [email protected] Abstract: Besides the geometrical errors, interferometry suffers errors due to diffraction, because the wavefront aberrations of the test and reference beams change as they propagate. This paper addresses errors due to diffraction effects in inter...
متن کاملPrecision Length Measurements by Multi-Wavelength Interferometry
Three different applications of multi-wavelength interferometry are reviewed which have been developed at PTB. They demonstrate the high precision achievable by this technique on multiple scales, from absolute geodetic distances up to 10 m, over prismatic bodies, e.g. gauge blocks, in the sub-meter regime, down to the microscopic roughness of surfaces.
متن کاملLaser plasma density measurements using interferometry
Fabrication of an interferometer is planned at the UCSD Laser Plasma and Laser-Matter Interactions Laboratory. The primary goal of this project is to measure the density at early times in the evolution of highly transient laser created plasmas. We describe the design concepts and details of different kinds of interferometer for measuring density evolution, especially during early time of plasma...
متن کاملMeasuring the deposited energy from a non-ionizing laser beam in water by digital holographic interferometry
Digital Holographic interferometry is a powerful and widely used optical technique for accurate measurement of variations in physical quantities such as density, refractive index, and etc. In this study, an experimental digital holographic interferometry setup was designed and used to measure the amount of energy changes induced by absorption of radiation from a non-ionizing infrared laser beam...
