A novel approach is presented in this paper based on the double-beam frequency-shift feedback of the laser, which can completely eliminate the dead path errors and measure the displacement or vibration with accuracy at nanometer scale even at a far measurement distance. The two beams emitted from one Nd:YVO4 crystal are incident on the measurement target and its adjacent reference surface, respectively. The reference surface could be taken from the nearby stationary object, without the need to put a reference mirror. The feedback paths and shift frequencies of the two beams are the same, so the air disturbances and the thermal effects in the way could be fully compensated. Under common room conditions, the displacement of a steel block at a distance of 10 m is measured, which proved that the system\u2019s stability is \u00b112 nm in 100 s and \u00b150 nm in 1000 s, the short-term resolution is better than 3 nm, and the linearity within the 300 mm range is 5 \u00d7 10\u22126 and within the 100 \u03bcm range is 1 \u00d7 10\u22124.<\/jats:p>","DOI":"10.1063\/1.5001207","type":"journal-article","created":{"date-parts":[[2018,3,15]],"date-time":"2018-03-15T15:36:14Z","timestamp":1521128174000},"update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":8,"title":["Full path compensation laser feedback interferometry for remote sensing with recovered nanometer resolutions"],"prefix":"10.1063","volume":"89","author":[{"given":"Ling","family":"Xu","sequence":"first","affiliation":[{"name":"The State Key Lab of Precision Measurement Technology and Instrument, Department of Precision Instruments, Tsinghua University , Beijing 100084, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yidong","family":"Tan","sequence":"additional","affiliation":[{"name":"The State Key Lab of Precision Measurement Technology and Instrument, Department of Precision Instruments, Tsinghua University , Beijing 100084, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shulian","family":"Zhang","sequence":"additional","affiliation":[{"name":"The State Key Lab of Precision Measurement Technology and Instrument, Department of Precision Instruments, Tsinghua University , Beijing 100084, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"317","published-online":{"date-parts":[[2018,3,15]]},"reference":[{"key":"2023070420590638200_c1","doi-asserted-by":"publisher","first-page":"706","DOI":"10.1109\/68.766792","volume":"11","year":"1999","journal-title":"IEEE Photonics Technol.
