Spectrally multiplexed photothermal OCT and novel detection methods


Journal Article

We demonstrate simultaneous detection of two nanoparticle species using phasesensitive optical coherence tomography with photothermal excitation at two wavelengths matched to the distinct absorption peaks of the nanoparticles. To minimize bulk heating of the sample, a novel single-pulse excitation scheme is proposed and its sensitivity is characterized. © OSA 2012.
