A laser interferometer measurement system and measurement method, the laser emits laser light; long rectangular mirror mounted on the side of the loading station, which the two reflective surfaces and stage horizontal plane 45 °, in the horizontal direction of the incident laser rectangular strip ...
aA laser interferometer measurement system and an electronic differential level were used to measure machine linkage errors. Those errors include linear errors of feed mechanisms, straightness errors of guideways, angular errors of machine slides, out-of-squareness errors among machine axes, thermal expan...

Michelson interferometer system for seismic noise measurement Laser interferometry is one of the most sensitive and widely used techniques for small displacement measurement, whose success is mainly due its very good ... Acernese,Fausto - International Society for Optics and Photonics 被引量: 2发表:...
The laser system presented here is an entirely commercial device that can be adapted to atom interferometer experiments using atomic rubidium, as well as potassium80and cesium81. These systems can be made more mobile and compact74for applications outside the laboratory; with the addition of micro-...
The measurement of a positioning stage with high precision is usually based on a laser interferometer.According to the principle of measurement,the measuring error of the interferometer should be about 1/3 to 1/2 of that in the positioning stage,so that the measuring results are believable only...
The orthogonal Michelson interferometer is used for homodyne laser vibration measurement system traditionally.However,it is difficult to remove error.A simple optical system was presentedin this paper.A quadrant detector(two pixels were used) was adopted.Since the two pixels of detector were in differe...
Laser interferometers have found wide usage in a variety of precision measurement applications. The ability to gain precise position information with minimal change to the dynamics of the device being measured has a large set of advantages. This allows interferometer systems to be used in feedback ...
FTIR open-path instrumentation consists of: an infrared source, an interferometer a set of transfer optics, the detector and signal processing electronics. The infrared beam is collimated and sent through the interferometer where all wavelengths are modulated. The beam is expanded by the telescope and...
