1. A pneumatic otoscopic imaging system comprising:

  • a. a source of light;

    b. a hand-held otoscope for abutment with an ear canal for directing the light to ear tissue and for collecting scattered light from the ear tissue;

    c. an interferometer for combining the scattered light from the ear tissue with a reference beam for generating an interferometry signal;

    d. a pneumatic port coupled to the hand-held otoscope for governing a pressure within the ear canal;

    e. a pump for varying the pressure within the ear canal;

    f. one of a pressure sensor and a pump controller for generating a pressure signal; and

    g. a processor for receiving the interferometry signal and the pressure signal and for generating therefrom a quantitative characterization of the ear tissue under a specified condition of pressure within the ear canal.
