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.

Frequency-domain optical coherence tomography with extended field-of-view and reduction of aliasing artifacts

An optical probe is provided. The optical probe includes a lens extending along an axis between a first end and a second end. A spacer extends along the axis between a first end and a second end. The first end of the spacer is connected to the second end of the lens. A prism is connected to the second end of the spacer such that the prism is spaced apart from the lens by the spacer.
