    Ultra-high speed full range complex spectral domain optical coherence tomography for volumetric imaging at 140,000 A scans per second
    We demonstrate an ultra-high speed full rang spectral domain optical coherence tomography system based on CMOS camera at 140,000 A-scans per second. By implementing beam-offset method, a constant modulation frequency is introduced into each B-scan that enables the reconstruction of the full range complex SDOCT images from in vivo biological specimens. To make use of the full acquisition capacity of detection camera used in the system, we developed system control software that streams the raw spectral fringe data directly into the computer memory. The feasibly of our high speed full range SDOCT system is demonstrated for imaging the dynamics ...
