AbstractWe report a 45 kHz spectroscopic OCT system based on a swept laser source utilizing two wavelength bands. The source is generated by single-band swept laser input and a fiber optical parametric amplifier. The time-multiplexing architecture reduces the complexity of the coupling and detecting configuration in comparison with the previous dual-band swept-source setup. This high-speed spectroscopic OCT combines the advantages of the speed of the swept laser and contrast enhancement, in comparison with the time or spectral-domain spectroscopic OCT system. In the experiment, spectroscopic OCT imaging around 1550 nm is achieved for the first time. The difference in images at 1500 nm and 1600 nm clearly shows different back scattering and penetration properties which can be used for tissue classification and water content measurement.
