Optical fiber-based optical splitter, system, splitter, pressure detection device and environment detection device

Abstract

The invention relates to the field of an optical devices and mainly introduces an optical splitter, a system, a splitter, a pressure detection device and an environment detection device based on optical fibers. The optical splitter comprises a first optical fiber core, a second optical fiber core and a transparent elastic layer. When whether the pressure of a to-be-detected object is balanced or not is detected, only the optical splitter needs to be placed below the to-be-detected object, a transparent elastic layer shrinks under the action of pressure, if the generated pressure is relativelybalanced, the contraction condition of the transparent elastic layer is consistent, the proportions of emergent light at two ends of the second optical fiber core are the same, when the optical splitter is used for detecting whether the pressure of the to-be-detected object is balanced or not, only the light needs to be input into an incident end of the first optical fiber core, then two ends of the second optical fiber core are used for detecting the emergent light, and whether the pressure of the to-be-detected object is balanced or not can be simply and accurately obtained according to theproportions of the emergent light at the two ends of the second optical fiber core.

Description

technical field [0001] The invention relates to the field of optical devices, and mainly introduces an optical splitter, a system, a splitter, a pressure detection device and an environment detection device based on an optical fiber. Background technique [0002] Optical splitters are passive devices, they require no external energy, only input light. The beam splitter consists of entrance and exit slits, mirrors and dispersive elements, and its function is to separate the required resonant absorption lines. The key component of the spectrometer is the dispersive element, and now commercial instruments use gratings. [0003] In the prior art, the method for detecting whether the pressure of the object to be measured is balanced is to place strain gauges at multiple positions under the object to be measured, and obtain whether the pressure of the object to be measured is balanced through the measurement of multiple strain gauges. [0004] However, when detecting whether the...

Problems solved by technology

[0005] The purpose of the present invention is to provide a fiber-based optical splitter and system to solve the problems in the prior art that the strain gauges are easily damaged during use when detecting whether the pressure of the object to be measured is balanced. It makes the measurement data inaccurate, and in addition, the cost of setting multiple strain gauges at the bottom of the object to be measured is high
