Abstract

PROBLEM TO BE SOLVED: To provide sonoluminescence probe employing an optical fiber for measuring sonoluminescence phenomenon of ultrasonic wave and measuring the intensity of ultrasonic wave by correlating sonic field with chemical reaction. SOLUTION: A water bag 1 made of a material passing a sound wave well, e.g. polyethylene, is encapsulated with water and then fixed with an optical fiber 3 such that the optical fiber 3 touches the water. The optical fiber 3 is connected with a photodiode 4 having output connected with a measuring unit 6 through a cable 5. Ultrasonic wave generated from an ultrasonic oscillator is transmitted into the water bag 1 and to the water 2 or luminol solution in the water bag 1 thus generating a cavitation. Light generated from the cavitation is passed through the optical fiber 3 and detected by the photodiode 4. The measuring unit 6 receives an electric signal from the photodiode 4 and measures a sonic field generated from the ultrasonic oscillator in the small water bag at fine point.
