Abstract
We report a new yet simple method to achieve full-range complex Fourier-domain optical coherence tomography (OCT) for in vivo imaging. The method utilizes a scanner that is dedicated for lateral scanning in the system to introduce a constant carrier frequency into the OCT spectral interferograms during the scanning. This is achieved by simply offsetting the sampling beam spot away from the pivot point of the scanning mirror. We demonstrate the method experimentally for in vivo full-range imaging of the anterior segment of a human eye. The method is free from complex conjugate mirror image and self-cross-correlation image artifacts.
