Abstract

A method and a system for Uniform Frequency Sample Clocking to directly sample the OCT signal with a temporally-non-linear sampling clock derived from a k-space wavemeter on the external sample clock input port of a digitizer. The Uniform Frequency Sample Clocking comprises at least one Pathway, which includes characterizing the swept light source, creating a digital representation of the waveform based from the characterization data, and generating a clock signal using a waveform generator to output the clock signal to a digitizer external clock.
