Such interferometers suffer from environmental effects because of the different phase changes induced in different optical paths and consequently the measurement precision will be significantly influenced by tiny variations of the environmental conditions. Fabry-Perot interferometers, which feature common optical paths, are insensitive to environmental disturbances. That would be advantageous for precision displacement measurements under ordinary environmental conditions. To verify and analyze this influence, displacement measurements with the two types of interferometers, i.e., a self-fabricated Fabry-Perot interferometer and a commercial Michelson interferometer, have been performed and compared under various environmental disturbance scenarios. Under several test conditions, the self-fabricated Fabry-Perot interferometer was obviously less sensitive to environmental disturbances than a commercial Michelson interferometer. Experimental results have shown that induced errors from environmental disturbances in a Fabry-Perot interferometer are one fifth of those in a Michelson interferometer. This has proved that an interferometer with the common optical path structure will be much more independent of environmental disturbances than those with a non-common optical path structure. It would be beneficial for the solution of interferometers utilized for precision displacement measurements in ordinary measurement environments.<\/jats:p>","DOI":"10.3390\/s100402577","type":"journal-article","created":{"date-parts":[[2010,3,24]],"date-time":"2010-03-24T12:14:57Z","timestamp":1269432897000},"page":"2577-2586","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":31,"title":["The Comparison of Environmental Effects on Michelson and Fabry-Perot Interferometers Utilized for the Displacement Measurement"],"prefix":"10.3390","volume":"10","author":[{"given":"Yung-Cheng","family":"Wang","sequence":"first","affiliation":[{"name":"Institute of Mechanical Engineering, National Yunlin University of Science and Technology, Douliou, Yunlin County 640, Taiwan"}]},{"given":"Lih-Horng","family":"Shyu","sequence":"additional","affiliation":[{"name":"Institute of Mechanical and Electro-Mechanical Engineering, No.64, Wunhua Rd., Huwei Township, Yunlin County 632, Taiwan"}]},{"given":"Chung-Ping","family":"Chang","sequence":"additional","affiliation":[{"name":"Institute of Mechanical Engineering, National Yunlin University of Science and Technology, Douliou, Yunlin County 640, Taiwan"}]}],"member":"1968","published-online":{"date-parts":[[2010,3,24]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"3809","DOI":"10.1364\/OL.34.003809","article-title":"Common-path laser interferometer","volume":"34","author":"Qu","year":"2009","journal-title":"Opt.
