Abstract
A nonreciprocal fiber-optic interferometer is demonstrated in an optical co herence tomography (OCT) system. The increased power efficiency of this sys tem provides a 4.1-dB advantage over standard Michelson rotary optical junc tion that is required in circumferential scanning systems. These advancemen ts have permitted the clinical implementation of OCT imaging in the human g astrointestinal tract. (C) 1999 Optical Society of America.
