ScholarBank@NUS Repository. https://doi.org/10.1364/OE.20.006325 | Abstract: | A novel prototype of an electrothermal chevron-beam actuator based microelectromechanical systems (MEMS) platform has been successfully developed for circumferential scan. Microassembly technology is utilized to construct this platform, which consists of a MEMS chevronbeam type microactuator and a micro-reflector. The proposed electrothermal microactuators with a two-stage electrothermal cascaded chevron-beam driving mechanism provide displacement amplification, thus enabling a highly reflective micro-pyramidal polygon reflector to rotate a large angle for light beam scanning. This MEMS platform is ultra-compact, supports circumferential imaging capability and is suitable for endoscopic optical coherence tomography (EOCT) applications, for example, for intravascular cancer detection. © 2012 Optical Society of America. | Source Title: | Optics Express | URI: | http://scholarbank.nus.edu.sg/handle/10635/59732 | ISSN: | 10944087 | DOI: | 10.1364/OE.20.006325 |
