Optical whispering gallery mode (WGM) resonator-based acoustic sensors, imaging systems that make use of the acoustic sensors, and methods of detecting ultrasound waves using the acoustic sensors are disclosed.

Ultrasound sensing and imaging based on whispering-gallery-mode (WGM) microresonators

Optical fiber based acoustic sensors are provided herein. The optical fiber based acoustic sensors described herein include acoustically responsive optical structures configured to detect and receive acoustic signals, including ultrasound signals, and provide associated optical signals to a system for processing and interpretation to implement tracking, location, and imaging capabilities. Optical fiber based sensors provided herein may be disposed at ends of or along the length of optic fibers. Optical fiber based sensors may be included within various devices, including, for example, medical devices. Optical fiber based sensors may provide a compact technology with high sensitivity to visualize and track objects and provide anatomical imaging.
