Otitis Media (OM) is related to a group of inflammatory diseases of the middle ear (ME) commonly encountered, worldwide. A method based on a simple device, which can be used by medical staff and non-experts to detect OM is presented. The method is based on detection of tympanic membrane (TM) vibrations. A laser beam is pointed on an infra-sonic stimulated TM with fast camera capturing the back scattered secondary speckle patterns. A camera enables inspection of the frequency and amplitude of the changes in TM characteristics obtained by analysis of the spatial-temporal statistics of the speckle patterns. The results may provide information that express ME effusion.
