Abstract

The invention discloses compressive optical fiber for ultrasonic sonoluminescence signal detection. The compressive optical fiber comprises an optical fiber body, wherein the optical fiber body comprises an optical fiber beam and a protective layer which is arranged outside the optical fiber beam and used for compressive waterproofness, the optical fiber beam comprises at least two single-core optical fibers, and a sealant for sealing is arranged in a clearance between the optical fiber beam and the protective layer. The compressive optical fiber comprises the at least two single-core opticalfiber parts, so that the transmission core diameter is increased, light emitted by ultrasonic cavitation can be easily coupled into the optical fiber, a light signal suitable for spectrum detection can be collected, and the optical fiber has low absorption on the light from an ultraviolet region to a visible light region and have a good light transmission effect. The compressive optical fiber caneffectively guide a sonoluminescence signal generated by an ultrasonic transducer out to an optical detection device; and the compressive optical fiber can guide the light to the outer portion of a pressurization tank for detection under the hydrostatic pressure of 0-100 standard atmospheric pressure.

Description

technical field [0001] The invention belongs to the technical field of ultrasonic sonoluminescence signal detection, and in particular relates to a pressure-resistant optical fiber used for ultrasonic sonoluminescence signal detection. Background technique [0002] Ultrasonic sonoluminescence is a phenomenon produced by ultrasonic cavitation. The intensity of luminescence is related to factors such as ultrasonic frequency, electric power of ultrasonic transducer, hydrostatic pressure, and oxygen capacity of ultrasonic water medium or other liquid medium. The understanding of the phenomenon of ultrasonic sonoluminescence is mainly studied by detecting the intensity, spectrum and periodicity of the luminescence. It is difficult to test the optical signal directly outside the pressurized tank, as long as the working medium used by ultrasound is water or other liquid media, when light is transmitted through water or other liquid media and the glass observation window on the pres...
