Miniature forward-viewing spectrally encoded endoscopic probe

Opt Lett. 2014 Aug 15;39(16):4871-4. doi: 10.1364/OL.39.004871.

Abstract

Spectrally encoded endoscopy is a promising technique for minimally invasive imaging, allowing high-quality imaging through small diameter probes that do not require rapid mechanical scanning. A novel optical configuration that employs broadband visible light and dual-channel imaging is used to demonstrate a miniature forward-viewing probe having a high number of resolvable points, low speckle contrast, negligible backreflections, and high signal-to-noise ratio. The system would be most suitable for imaging through narrow ducts and vessels for clinical diagnosis at hard-to-reach locations in the body.
