The inner ear is a small and sophisticated organ, mainly comprising of the vestibular system and cochlea, responsible for hearing function and plays a crucial role in the life wellness.There have been several studies of investigating the cochlear structures with OCT, and most of these studies used OCT systems with a central wavelength of 1.3 µm. However, the utility of 1 µm OCT system for cochlear imaging application has yet been explored albeit the capability of providing OCT images with a higher axial resolution. Therefore, in this study, we have developed a 1.3 µm and a 1 µm OCT system allowing quantitative and spectroscopic comparison of the cochlear microstructures.
