Hearing impairment and loss are widespread conditions that impact a significant portion of the global population, greatly diminishing both communication abilities and overall quality of life. These auditory issues are most commonly associated dysfunctions within the cochlea of the inner ear. Achieving non-destructive imaging of the cochlea’s internal structure with adequate spatial resolution remains a significant challenge. To address this, we successfully conducted the first non-destructive terahertz (THz) imaging of a mouse cochlea using a THz near-field point source microscope capable of micro-scale resolution. High-accuracy three-dimensional (3D) THz time-of-flight (ToF) imaging and reconstruction were also demonstrated. This advancement lays the groundwork for future medical diagnostic applications, particularly in the early detection and evaluation of hearing-related disorders.
