OPTICAL DETECTION OF MIDDLE EAR EFFUSION AND INFECTION

Abstract

An optical detection system for diagnosis of ear conditions includes a first light source that emits light of a first wavelength and a second light source that emits light of a second wavelength that differs from the first wavelength. An imaging device is positioned proximate to the first light source and the second light source. The imaging device is sized to fit within an ear canal of a patient to capture one or more images within an ear of the patient. A processor is in communication with the imaging device and configured to analyze the one or more images to identify a laser speckle pattern in the one or more images and determine a diagnosis for the patient based at least in part on the laser speckle pattern identified in the one or more images.
