Abstract:
The present disclosure provides an OCT imaging system to reduce or eliminate frequency-domain aliasing artifacts. The frequency is shifted using a carrier frequency to define a sampling range substantially centered on the carrier frequency. An image of the sample is generated from a displayed imaging range that consists of a subset of the frequencies within the sampling range. Furthermore, the system may be configured to determine the carrier frequency such that a Nyquist frequency corresponding to the shifted frequency is extended beyond either an upper or a lower bound of an OCT quality envelope corresponding to the first portion of light. Additionally, the carrier frequency may be determined such that a lower bound of the OCT quality envelope is greater or less than a zero-frequency DC limit.

Claim (Index 15):
A frequency-domain optical coherence tomography (OCT) system for optically imaging a sample, comprising:\n an optical source configured to emit output light over a range of wavelengths; and an interferometer configured to detect interference over a sampling range of frequencies each associated with a different depth within the sample, the optical source further configured to illuminate the sample with a first portion of the output light and to illuminate a reference plane with a second portion of the output light, the interferometer further configured to associate larger depths within the sample with more negative frequencies within the sampling range, wherein the sampling range extends from a first frequency to a second frequency and is substantially centered on a carrier frequency.
