Claim 0:
1. A method of bulk motion compensation of phased-based functional optical coherence tomography (OCT), the method comprising:
receiving, via an OCT system, a first complex-valued OCT A-scan, An, associated with a sample;
receiving, via the OCT system, a second complex-valued OCT A-scan, An+1, associated with the sample;
determining a set of variance values for the first and second complex-valued OCT A-scans at different phases;
determining a bulk motion phase shift, ΔϕB, from the set of variance values;
performing bulk motion compensation on the first and second complex-valued OCT A-scans using the bulk motion phase shift, ΔϕB; and
generating a flow image of the sample based on the bulk motion compensated first and second complex-valued OCT A-scans.
