Unusual techniques for absolute distance measurement

چکیده
Peter de Groot Zygo Corporation Research and Development Department 21 Laurel Brook Road Middlefield, Connecticut 06455 Abstract. I describe four unusual laser systems for absolute measures of linear distance. All employ the familiar techniques of multiple wavelengths, chirped wavelength, optical feedback and intensity modulation, but in somewhat unfamiliar architectures. These examples serve to illustrate the breadth of solutions to this important problem. © 2001 Society of Photo-Optical Instrumentation Engineers. [DOI: 10.1117/1.1330702]

A 4% geometric distance to the galaxy NGC4258 from orbital motions in a nuclear gas disk
The accurate measurement of extragalactic distances is a central challenge of modern astronomy, being required for any realistic description of the age, geometry and fate of the Universe. The measurement of relative extragalactic distances has become fairly routine, but estimates of absolute distances are rare. In the vicinity of the Sun, direct geometric techniques for obtaining absolute dista...
متن کاملHigh-precision Absolute Distance Measurement using Frequency Scanned Interferometry
In this letter, we report high-precision absolute differential distance measurements performed with frequency scanned interferometry (FSI). Absolute differential distance was determined by counting the interference fringes produced while scanning the laser frequency. A high-finesse Fabry-Perot interferometer was used to determine frequency changes during scanning. Two new multi-distance-measure...
