High-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...
متن کاملMoving Target Search Algorithm with Informational Distance Measures
We consider an Ishida and Korf Moving Target Search (MTS) algorithm with informational distance measures. Similarly to the previously defined Informational Learning Real-Time A* algorithm, the suggested algorithm acts on the set of partitions of the sample space, on which the probability mass function is defined. The information-based Rokhlin metric and its lower bound – Ornstein metric, give t...
متن کاملHigh-precision absolute distance and vibration measurement with frequency scanned interferometry.
We report high-precision absolute distance and vibration measurements performed with frequency scanned interferometry using a pair of single-mode optical fibers. Absolute 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 multiple-distance...
متن کاملHigh Precision Optical Measurement Methods
I. INIRODllCTION Noncontact optical methods are appropriate for mic;ro.. and macrostructure measurements. Time of flight and phase measuring techniques with a resolution in the order of a few mm to one mm. respectively arc well introduced. Furthermore active and passive triangulation techniques arc very robust and appropriate for different applications in precision measurements. Some optical 3-...
متن کاملPrecision measurement with an optical Josephson junction
We study a new type of Josephson device, the so-called “optical Josephson junction” as proposed in Phys. Rev. Lett. 95, 170402 (2005). Two condensates are optically coupled through a waveguide by a pair of Bragg beams. This optical Josephson junction is analogous to the usual Josephson junction of two condensates weakly coupled via tunneling. We discuss the use of this optical Josephson junctio...
