| Popis: | Non-scanning optical coherence tomography based on off-axis interferometry has been developed for real-time depth-resolved imaging. By incorporating an angular-dispersion imaging scheme with a phase-shift detection technique, we show that amplitude of the interferogram corresponding to the reflectance of the sample can be detected directly with a CCD camera. Longitudinal cross-sectional images acquired at the rate of 5 Hz are presented. |
