Brief
This article describes the development and experimental validation of a miniaturized ultrasonic sensor based on a Fabry-Pérot cavity fabricated on the end face of a double-clad fiber using two-photon three-dimensional lithography, demonstrating its feasibility for high-precision ultrasonic signal detection with potential applications in biomedical imaging, particularly photoacoustic endoscopy.
Summary
Researchers developed a tiny, highly sensitive ultrasonic sensor based on a Fabry-Pérot cavity fabricated on the end of a double-clad fiber using 3D printing for precise acoustic signal detection, particularly for use in miniaturized medical imaging tools like photoacoustic endoscopes to improve early disease diagnosis.
