Method and apparatus for locating foreign objects in the ear canal

摘要

The invention concerns a method for locating foreign objects on the internal surface of ear and ear canal whereby a probe having a light emitting distal portion is inserted into the ear canal, the method further comprising the steps of directing light from the distal portion of the probe to illuminate at least one point or the internal circumferential surface of the ear and/or car canal, receiving the light reflected from the illuminated surface, and directing the received light to at least one light sensitive element to generate an output, analyzing the output with respect to spectral composition in order to identify foreign objects. The invention also relates to an apparatus for locating foreign objects on the internal surface of ear and ear canal.
