The TeCE camera can execute a very short exposure multiple times at an arbitrary timing during one shot. Furthermore, by accumulating the photoelectrons generated by each exposure, it is possible to maintain the brightness even with a short exposure time. By synchronously driving the TeCE camera and the TAG lens, different focal planes of an observation target can be acquired at high speed. As a result, high-speed three-dimensional measurement becomes possible, and this can be used for feedback of three-dimensional information. In the work described in this paper, we conducted a focus tracking experiment to evaluate the feedback performance of the TeCE camera. From the experimental results, we confirmed the feedback capability of the TeCE camera.<\/jats:p>","DOI":"10.3390\/s19071606","type":"journal-article","created":{"date-parts":[[2019,4,4]],"date-time":"2019-04-04T03:13:42Z","timestamp":1554347622000},"page":"1606","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Fast Volumetric Feedback under Microscope by Temporally Coded Exposure Camera"],"prefix":"10.3390","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1126-9094","authenticated-orcid":false,"given":"Kazuki","family":"Yamato","sequence":"first","affiliation":[{"name":"Graduate School of Science and Technology, Gunma University, 1-5-1, Tenjin-cho, Kiryu 376-8515, Japan"}]},{"given":"Toshihiko","family":"Yamashita","sequence":"additional","affiliation":[{"name":"Graduate School of Science and Technology, Gunma University, 1-5-1, Tenjin-cho, Kiryu 376-8515, Japan"}]},{"given":"Hiroyuki","family":"Chiba","sequence":"additional","affiliation":[{"name":"Graduate School of Science and Technology, Gunma University, 1-5-1, Tenjin-cho, Kiryu 376-8515, Japan"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4013-7373","authenticated-orcid":false,"given":"Hiromasa","family":"Oku","sequence":"additional","affiliation":[{"name":"Graduate School of Science and Technology, Gunma University, 1-5-1, Tenjin-cho, Kiryu 376-8515, Japan"}]}],"member":"1968","published-online":{"date-parts":[[2019,4,3]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Ohara, K., Kojima, M., Takagi, S., Horade, M., Mae, Y., and Arai, T.
