The linear array was fabricated using Si-SOI bonding techniques. Underwater transmission performance was tested in a water tank, and the array has a resonant frequency of 700 kHz, with pressure amplitude 182 dB (\u03bcPa\u00b7m\/V) at 1 m. The \u22123 dB main beam width of the designed dense linear array is approximately 5 degrees. Synthetic aperture focusing technique was applied to improve the resolution of reconstructed images, with promising results. Thus, the proposed array was shown to be suitable for underwater imaging applications.<\/jats:p>","DOI":"10.3390\/s16030312","type":"journal-article","created":{"date-parts":[[2016,3,1]],"date-time":"2016-03-01T11:07:19Z","timestamp":1456830439000},"page":"312","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":17,"title":["Underwater Imaging Using a 1 \u00d7 16 CMUT Linear Array"],"prefix":"10.3390","volume":"16","author":[{"given":"Rui","family":"Zhang","sequence":"first","affiliation":[{"name":"Key Laboratory of Instrumentation Science &amp; Dynamic Measurement, North University of China, Ministry of Education, Taiyuan 030051, China"},{"name":"Science and Technology on Electronic Test and Measurement Laboratory, North University of China, Taiyuan 030051, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1762-9246","authenticated-orcid":false,"given":"Wendong","family":"Zhang","sequence":"additional","affiliation":[{"name":"Key Laboratory of Instrumentation Science &amp; Dynamic Measurement, North University of China, Ministry of Education, Taiyuan 030051, China"},{"name":"Science and Technology on Electronic Test and Measurement Laboratory, North University of China, Taiyuan 030051, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Changde","family":"He","sequence":"additional","affiliation":[{"name":"Key Laboratory of Instrumentation Science &amp; Dynamic Measurement, North University of China, Ministry of Education, Taiyuan 030051, China"},{"name":"Science and Technology on Electronic Test and Measurement Laboratory, North University of China, Taiyuan 030051, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yongmei","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Computer Science, North China University of Technology, Beijing 100144, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jinlong","family":"Song","sequence":"additional","affiliation":[{"name":"Key Laboratory of Instrumentation Science &amp; Dynamic Measurement, North University of China, Ministry of Education, Taiyuan 030051, China"},{"name":"Science and Technology on Electronic Test and Measurement Laboratory, North University of China, Taiyuan 030051, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chenyang","family":"Xue","sequence":"additional","affiliation":[{"name":"Key Laboratory of Instrumentation Science &amp; Dynamic Measurement, North University of China, Ministry of Education, Taiyuan 030051, China"},{"name":"Science and Technology on Electronic Test and Measurement Laboratory, North University of China, Taiyuan 030051, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2016,3,1]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"770","DOI":"10.1016\/j.mejo.2005.10.012","article-title":"Capacitive micromachined ultrasonic transducer (CMUT) arrays for medical imaging","volume":"37","author":"Caronti","year":"2006","journal-title":"Microelectron.
