摘要：
Ultrahigh resolution, real time OCT imaging is demonstrated using a compact femtosecond Nd:Glass laser that is spectrally broadened in a high numerical aperture single mode fiber. A reflective grating phase delay scanner enables broad bandwidth, high-speed group delay scanning. We demonstrate in vivo, ultrahigh resolution, real time OCT imaging at 1 mum center wavelength with <5 mu m axial resolution in free space (<4 mum in tissue). The light source is robust, portable, and well suited for in vivo imaging studies.
