Absolute measurement of a long, arbitrary distance to less than an optical fringe.
نویسنده
چکیده
A scheme is proposed for high-precision, absolute length measurement for an arbitrary optical distance of a few meters to beyond 10(6) m. The approach utilizes a phase-stabilized femtosecond laser to provide both incoherent, time-of-flight information and coherent, fringe-resolved interferometry. Such a combined measurement capability allows an optical wavelength resolution to be achieved for absolute length measurement over a large dynamic range.

Data interrogation for Fabry-Perot whitelight interferometry
Among various optical fiber distance sensing techniques, optical fiber sensors based on white-light Fabry-Perot interferometry offer the simplest configuration, the highest sensitivity, and the most precise distance measurement. Because a whitelight interferometric sensor can overcome the directional ambiguity problem encountered by the other interferometric techniques, it is especially attract...
متن کاملMode-resolved frequency comb interferometry for high-accuracy long distance measurement
Optical frequency combs have developed into powerful tools for distance metrology. In this paper we demonstrate absolute long distance measurement using a single femtosecond frequency comb laser as a multi-wavelength source. By applying a high-resolution spectrometer based on a virtually imaged phased array, the frequency comb modes are resolved spectrally to the level of an individual mode. Ha...

A heterodyne interference system is developed for base-lines measurement by using an acoustic optical modulator and a stabilized optical-frequency comb. The temporal coherence interference with the optical-frequency comb happen at discrete positions, where a pair of pulse trains overlaps with each other. An optical delay of the interferometer with a piezo-electric transducer is realized to find...

Comparison and frequency shift experiments have been done for a distance of about 7.493 m. The experimental results show tha...
متن کاملDevelopment of an in-fiber white-light interferometric distance sensor for absolute measurement of arbitrary small distances.
The fabrication, implementation, and evaluation of an in-fiber white-light interferometric distance sensor that is capable of measuring the absolute value of an arbitrary small distance are presented. Taking advantage of the mode-coupling effect of a long-period fiber grating, an additional cavity distance is added to the optical path difference of the distance sensor; therefore, it can generat...
