Abstract

Full-range spectral domain optical coherence tomography (SD-OCT) with a 1-μm 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 μm in air and the sensitivity was 99.4 dB. To demonstrate the effect of mirror image elimination, in vivo human eye pathology was measured.
