AbstractA novel method of simultaneous multi-wavelength-band common-path optical frequency domain imaging is proposed for spectroscopic applications. Simultaneous multi-band wavelength tuning can be performed by using multiple fiber-ring cavities with corresponding optical semiconductor amplifier as their gain mediums and narrowband optical filters with a single polygonal scanner for synchronization. A simultaneous 1310/1550 dual-band swept laser source is constructed as a proof concept prototype. Broadband 1310/1550 wavelength-division multiplexing is used for coupling two wavelengths into a common-path single-mode GRIN-lensed fiber probe to form a dual-band common-path optical frequency domain imaging. Simultaneous imaging at 1310 and 1550 nm is achieved by using a depth ratio correction method. This technique allows potential for in vivo endoscopic high-speed functional optical frequency domain imaging with high quality spectroscopic contrast with low computational costs. On the other hand, the common path configuration is able to suppress common mode noise and potentially implement high stability quantitative phase measurements.
