Claim Text:
1. A method for controlling an electromagnetic radiation source of an optical coherence tomography (OCT) system to produce a radiation sweep having an optimized side-mode suppression ratio over a continuous range of wavelengths within a prescribed temporal profile, the electromagnetic radiation source configured to output electromagnetic radiation at a given wavelength based upon parameters, the method comprising: controlling the electromagnetic radiation source to emit electromagnetic radiation based on a group of parameter combinations, wherein uncontrolled parameters affect the emitted electromagnetic radiation; measuring the electromagnetic radiation source output for each parameter combination in the group of parameter combinations to determine a wavelength and a side-mode suppression ratio for each parameter combination in the group of parameter combinations; determining a set of parameter combinations that satisfy a condition for a desired set of wavelengths and a maximum side mode suppression ratio over the range of wavelengths, wherein: controlling the electromagnetic radiation source to emit electromagnetic radiation over the range of wavelengths by traversing the multivariate path in a desired manner; wherein the desired manner is linearly increasing or decreasing wavelength or optical frequency as a function of time or another indexing parameter of the sweep, and the electromagnetic radiation source outputs the electromagnetic radiation having the optimized side-mode suppression ratio over the range of wavelengths.
