Abstract
Methods and apparatus for identifying microbiological constituents in the middle ear. A spectrometer receives Raman-scattered light from the region of the tympanic membrane and resolves spectral features of the Raman-scattered light. A processor receives the interferometry signal and the Raman signal, and generates a Raman spectrum of the tympanic membrane and material adjacent thereto. In some embodiments of the invention, low-coherence light and substantially monochromatic excitation light are directed onto a tympanic membrane of the ear of a person via an otoscopic tip that abuts the ear canal. An interferometer combines scattered low-coherence light from the ear tissue with a reference signal to generate an interferometric signal.
