    J Biomed Opt. 2008 March/April;13(2):020505

    Authors: Han S, Sarunic MV, Wu J, Humayun M, Yang C

    We report the narrowest to-date (21 gauge, 820-mum-diam) handheld forward-imaging optical coherence tomography (OCT) needle endoscope and demonstrate its feasibility for ophthalmic OCT inspection. The probe design is based on paired-angle-rotation scanning (PARS), which enables a linear B-scan pattern in front of the probe tip by using two counterrotating angle polished gradient-index (GRIN) lenses. Despite its ... (Read Full Article)
