We have also demonstrated that 3D surface information for two different areas could be well obtained in a same time with only one camera by our method. In this study, double field of views (FOVs) of 11.16 mm \u00d7 5.92 mm were achieved within 0.5 s. Height range for each FOV was 460 \u00b5m and axial and transverse resolutions were 3.6 and 5.52 \u00b5m, respectively.<\/jats:p>","DOI":"10.3390\/s16010129","type":"journal-article","created":{"date-parts":[[2016,1,22]],"date-time":"2016-01-22T11:36:13Z","timestamp":1453462573000},"page":"129","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Parallel Imaging of 3D Surface Profile with Space-Division Multiplexing"],"prefix":"10.3390","volume":"16","author":[{"given":"Hyung","family":"Lee","sequence":"first","affiliation":[{"name":"Department of Cogno-Mechatronics Engineering, Pusan National University, Busan 609-735, Korea"}]},{"given":"Soon-Woo","family":"Cho","sequence":"additional","affiliation":[{"name":"Department of Cogno-Mechatronics Engineering, Pusan National University, Busan 609-735, Korea"}]},{"given":"Gyeong","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Cogno-Mechatronics Engineering, Pusan National University, Busan 609-735, Korea"}]},{"given":"Myung","family":"Jeong","sequence":"additional","affiliation":[{"name":"Department of Cogno-Mechatronics Engineering, Pusan National University, Busan 609-735, Korea"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0584-1111","authenticated-orcid":false,"given":"Young","family":"Won","sequence":"additional","affiliation":[{"name":"Medical Device Development Center, Osong Medical Innovation Foundation, Cheongju, Chungbuk 361-951, Korea"}]},{"given":"Chang-Seok","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Cogno-Mechatronics Engineering, Pusan National University, Busan 609-735, Korea"}]}],"member":"1968","published-online":{"date-parts":[[2016,1,21]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"302","DOI":"10.1117\/12.164874","article-title":"Laser light stripe measurements assure correct piston assembly","volume":"1989","author":"Stein","year":"1993","journal-title":"Proc.
