Abstract

A novel OCT otoscope device is needed for measuring thickness changes of tympanic membrane, a structure that separates outer and middle ear. While the traditional otoscope imaging can only obtain a monocular view, the new otoscope is aimed at obtaining depth perception. This information will be crucial to early detect abnormal ear condition and prevent hearing loss (one third of older adults encounter it). Planar waveguide array structure, presented here, is designed for snapshot imaging spectrometer and full field optical OCT system. 2-photon polymerization (2PP) three dimensional (3D) printing is used to fabricate the structure. The benefits of using 2PP 3D printing include high degree of freedom in design, short manufacture time, and lower cost.
