Seminar Title: 

Functional and Morphological Imaging of the Middle and Inner Ear with Optical Coherence Tomography and Vibrometry

Abstract:

Optical Coherence Tomography and Vibrometry (OCTV) is an interferometric technique, much like laser Doppler vibrometry (LDV), which takes advantage of the exquisite sensitivity of the interferometric phase to measure small scale motion. Unlike LDV, it uses low coherence spectral interferometry to spatially resolve vibration and generate a morphological image. The spatial resolution is typically ~10 µm in all dimensions but can be varied by focusing the light more tightly and/or changing the spectral bandwidth of the light source. At each spatially resolved point, we can routinely measure vibrations with <100 pm sensitivity with sound stimuli under 50 ms and <5 pm with temporal averaging. With micron-scale spatial resolution and subnanometer sensitivity to vibration, it is well suited to measuring the spatially resolved vibratory response of both the inner and middle ear. In small animals, it is possible to image directly through the bone of the otic capsule for noninvasive spatially resolved vibrometry of the cochlear partition. In humans as well as small animals, it’s possible to image the tympanic membrane and ossicles through the ear canal to reveal the vibratory response of the middle ear.
