|Title:||Double-reflection polygon mirror for high-speed optical coherence microscopy||Authors:||Liu, L.
|Issue Date:||15-Dec-2007||Citation:||Liu, L.,Chen, N.,Sheppard, C.J.R. (2007-12-15). Double-reflection polygon mirror for high-speed optical coherence microscopy. Optics Letters 32 (24) : 3528-3530. ScholarBank@NUS Repository.||Abstract:||We report on a high-speed, high-efficiency, high-duty-cycle, path-length-maintaining and linear beam scanner suitable for en face scanning optical coherence microscopy. Fast transverse beam scanning is achieved by use of a double-reflection polygon mirror (DRPM) rotating at a constant speed. With a motor speed of 18,000 rpm and a scanner diameter of 50 mm, the DRPM provides a line rate up to 3 kHz, ±1.8° scanning range, and 90% duty cycle. A much higher scanning speed and much larger scanning range can be readily achieved by increasing the scanner diameter. © 2007 Optical Society of America.||Source Title:||Optics Letters||URI:||http://scholarbank.nus.edu.sg/handle/10635/67009||ISSN:||01469592|
