Embodiment Construction

[0036] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0037] According to an embodiment of the present invention, a reflective optical fiber sensor device is provided. Such as Figure 1-Figure 13 As shown, this embodiment includes a light source 1 , a photodetector 3 and a sensor probe 2 , wherein: the sensor probe 2 receives the incident light from the light source 1 , and sends the resulting reflected light to the photodetector 3 after processing.

[0038] Further, in the above-mentioned embodiment, inside the sensor probe 2, a single-mode optical fiber (such as a single-mode optical fiber 41) and at least one multi-mode optical fiber arranged in parallel are packaged; wherein: the single-mode optical fiber 41 is use...

Abstract

The invention discloses a reflective optical fiber sensor device which comprises a light source, a light detector and a sensor probe, wherein the sensor probe is used for receiving incident light emitted by the light source and sending obtained reflected light to the light detector after processing the incident light. The reflective optical fiber sensor device disclosed by the invention can overcome the defects of large volume, incapability of application in the environment with electromagnetic interference, short service life, poor corrosion resistance and the like in the prior art so as to realize the advantages of small volume, wide application range, long service life and good corrosion resistance.

Description

technical field [0001] The present invention relates to sensors, in particular to a reflective optical fiber sensor device. Background technique [0002] With the rapid development of science and technology and the continuous improvement of people's living standards, in order to obtain information from the outside world, people must rely on sensory organs; and relying on people's own sensory organs alone, in the study of natural phenomena and laws and their functions in production activities It's not enough; to accommodate this situation, sensors have emerged. [0003] A sensor is a physical device or biological organ that can detect and sense external signals, physical conditions (such as light, heat, humidity) or chemical composition (such as smoke), and convert them into substances of the same or other nature according to certain rules. A device that outputs signals; it can be used in various fields such as fire protection, machinery, and construction. Its internal struc...
