Embodiment Construction

[0039]The present invention will be further described below in conjunction with the accompanying drawings and specific examples to better understand the invention and can be implemented, but the embodiments are not limited thereto.

[0040]ReferFigure 1 - Figure 4 As shown, the present invention discloses a sensing optical fiber 10, including a slim 20, and the slim 20 is axially disposed with a core 21, a first through hole 22, and a second through hole 23, a first through hole 22. The second through hole 23 is located on both sides of the core 21, and a gate region 24 is provided on the core 21, and the gate region 24 is written with a grating. Wherein, the end of the first through hole 22 is subjected to a colloid seal, and the end of the second through hole 23 is immersed in the liquid to be tested such that the gate region 24 is lower than the liquid surface to be tested, when the temperature and / or pressure of the liquid When there is a change, the reflection characteristics of...

Abstract

The invention discloses a sensing optical fiber, a sensing assembly, a sensor and a decoupling method thereof. The sensing optical fiber comprises a fiber body, the fiber body is provided with a fiber core, a first through hole and a second through hole along the axial direction of the fiber body, the first through hole and the second through hole are located at two sides of the fiber core, the fiber core is provided with a gate region, and the gate region is inscribed with a grating; and the end part of the first through hole is sealed by a colloid, the end part of the second through hole is immersed in a liquid to be detected so that the gate region is lower than the liquid level of the liquid to be detected, and when the temperature and / or pressure of the liquid are / is changed, the reflection characteristic of the grating of the gate region is changed so as to detect a physical signal. The structure is compact, a size is small, sensitivity is high, and the sensing optical fiber, the sensing assembly, the sensor and the decoupling method are suitable for detecting pressure and a temperature of the liquid in a narrow space.

Description

Technical field[0001]The present invention relates to the field of sensors, and more particularly to a sensor fiber, sensor assembly, sensor, and a decoupling method thereof.Background technique[0002]Sensor (English Name: Transducer / Sensor) is a detection device that can feel the measured information, and can feel the information that is used as an electrical signal or other desired information, in order to meet information. Requirements such as transmission, processing, storage, display, recording, and control.[0003]In the medical field, the temperature and pressure monitoring requirements in the human cavity channel are in the human natural cavity path of 3 mm in diameter, which can not accommodate the currently commonly used sensors, and use common endoscopic works[0004]Channel, even integrated with existing endoscopic mirrors, existing sensing device is more unable to meet.Inventive content[0005]The technical problem to be solved by the present invention is to provide a sensor...
