The dynamic surface shape of the VM has a direct impact on imaging quality and the optical modulation effect, so its measurement is necessary but also very difficult. Measurement of the dynamic surface shape of VMs requires a transiently acquired image series, but traditional methods cannot perform this task, as, when the VM is vibrating at a frequency of 3033 Hz, using high-speed cameras to acquire the images would result in frame rates exceeding 1.34 MFPS, which is currently technically impossible. In this paper, we propose the long exposure short pulse synchronous phase lock (LSPL) method, which can capture the dynamic surface shape using a camera working at 10 FPS. In addition, our proposed approach uses a single laser pulse and can achieve the dynamic surface shape measurement on a single frame image.<\/jats:p>","DOI":"10.3390\/s20092550","type":"journal-article","created":{"date-parts":[[2020,5,4]],"date-time":"2020-05-04T14:00:43Z","timestamp":1588600843000},"page":"2550","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Long Exposure Short Pulse Synchronous Phase Lock Method for Capturing High Dynamic Surface Shape"],"prefix":"10.3390","volume":"20","author":[{"given":"Weiqiang","family":"Han","sequence":"first","affiliation":[{"name":"Institute of Optics and Electronics of Chinese Academy of Sciences, Chengdu 610209, China"},{"name":"Key Laboratory of Science and Technology on Space Optoelectronic Precision Measurement, CAS, Chengdu 610209, China"},{"name":"University of Chinese Academy of Sciences, Beijing 100149, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiaodong","family":"Gao","sequence":"additional","affiliation":[{"name":"Institute of Optics and Electronics of Chinese Academy of Sciences, Chengdu 610209, China"},{"name":"Key Laboratory of Science and Technology on Space Optoelectronic Precision Measurement, CAS, Chengdu 610209, China"},{"name":"University of Chinese Academy of Sciences, Beijing 100149, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhenjie","family":"Fan","sequence":"additional","affiliation":[{"name":"Institute of Optics and Electronics of Chinese Academy of Sciences, Chengdu 610209, China"},{"name":"Key Laboratory of Science and Technology on Space Optoelectronic Precision Measurement, CAS, Chengdu 610209, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Le","family":"Bai","sequence":"additional","affiliation":[{"name":"Institute of Optics and Electronics of Chinese Academy of Sciences, Chengdu 610209, China"},{"name":"University of Chinese Academy of Sciences, Beijing 100149, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3084-0126","authenticated-orcid":false,"given":"Bo","family":"Liu","sequence":"additional","affiliation":[{"name":"Institute of Optics and Electronics of Chinese Academy of Sciences, Chengdu 610209, China"},{"name":"Key Laboratory of Science and Technology on Space Optoelectronic Precision Measurement, CAS, Chengdu 610209, China"},{"name":"University of Chinese Academy of Sciences, Beijing 100149, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2020,4,30]]},"reference":[{"key":"ref_1","first-page":"71","article-title":"Review of computer stereo vision technique","volume":"5","author":"Li","year":"1999","journal-title":"Opt.
