Abstract
A system for identifying vulnerable plaque includes an illumination subsystem for passing an illumination beam, modulated by a first modulation waveform, through a catheter. A receiving subsystem detects a collection beam, which is modulated by a second modulated waveform, from the catheter. A processing subsystem in communication with the receiving subsystem determines a relative phase difference between the first and second modulation waveforms.
