Development of a Miniaturized Otoscope for Middle Ear Diagnostics by High Speed Holography

Public

In the US, 17% of the adult population suffers from hearing loss. However, the diagnostic tools available make diagnosing middle-ear diseases extremely challenging. WPI's CHSLT is developing a high-speed holographic system capable of shape and displacement measurements of the tympanic membrane (TM) with nanometer-scale resolution. We developed an optical head for the system with an increased spatial resolution, depth-of-field, and miniaturized geometry. The prototype was developed using advanced optical software, validated and tested on a controlled sample, and finally integrated into the high-speed holographic system for measurements on a post-mortem human TM. The prototype met all design specifications and is successfully integrated into the system for future otologic research.
