Title:
SPR ULTRASONIC SENSOR AND ULTRASONIC MEASUREMENT SYSTEM
Document Type and Number:
WIPO Patent Application WO/2024/095808
Kind Code:
A1
Abstract:
An SPR ultrasonic sensor 110 comprises a prism 111 that allows a laser beam to pass therethrough and a metallic membrane 112 that reflects a laser beam. In the ultrasonic sensor, surface plasmon resonance is generated when a laser beam is incident on the metallic membrane 112, and the resonance angle is shifted when the metallic membrane 112 is irradiated with an ultrasonic wave. The ultrasonic sensor is characterized in that the metallic membrane 112 is formed only on a portion of a first surface 111A such that the area of a laser-beam irradiation spot formed on said surface 111A includes a metallic area and a non-metallic area.
