Optical Coherence Tomography Applications

An electronic optical imaging system consisting of a computer-controlled CCD array with 576 x 384 detection elements and 14 bits of digitization is presented. The system is used to obtain internal and external light intensity distributions for diffusing optical fiber tips used with photodynamic therapy and laser angioplasty. Significant intensity distribution variations were observed between fiber tips from 5 different sources. The effect of launch numerical aperture on the measured light distributions is also presented.
