摘要：

Full-range spectral domain optical coherence tomography (SD-OCT) with a 1-mu m band light source is demonstrated. The phase of reference arm is modulated simultaneously as the probing beam laterally scans the sample (B-scan). The obtained two dimensional spectral interferogram. is processed by Fourier transform method to obtain complex spectrum which leads to full-range OCT image. The measurement speed of this system was 7.96 kHz, the measured axial resolution was 9.6 mu m in air and the sensitivity was 99.4 dB. To demonstrate the effect of mirror image elimination, in vivo human eye pathology was measured.
