Abstract
A flat plate type optical fiber gas sensor is used for detection analysis of gas, and can confirm the elements and concentration of detected gas; relatively long optical path is beneficial to detection precision; conventional optical fiber gas sensors normally are cylindrical; reflectors are round; mount and adjustment are difficult; structures are complex. The flat plate type optical fiber gas sensor comprises an optical fiber collimator (1), a front reflector (2), a rear reflector (3) and a badeplate (4), and is characterized in that the shape of the front reflector (2) and the rear reflector (3) are similar to a cuboid; the front reflector (2) and the rear reflector (3) are provided with mount positioning surfaces, and are fixed on the baseplate (4) through the mount positioning surfaces. The flat plate type optical fiber gas sensor is convenient to adjust and simple in structure.
Description
Technical field
The present invention relates to a kind of flat fiber gas sensor, belong to optical measurement field.
Technical background
Fiber gas sensor, for the detection analysis of gas, can be determined composition and the concentration of tested gas, and longer light path is conducive to the precision detecting.

Innovation and creation content
Existing fiber gas sensor is all cylindrical shape conventionally, and catoptron is garden type, Installation and Debugging difficulty, complex structure.
Difference of the present invention be to provide a kind of adopt shape roughly the same rectangular parallelepiped catoptron, by its locating surface, be fixed on the flat Fibre Optical Sensor on substrate.Debugging is convenient, simple in structure.
Concrete scheme is: comprise optical fiber collimator (1), front mirror (2), back mirror (3), substrate (4).The shape of front mirror (2) and back mirror (3) is rectangular parallelepiped roughly the same, has installation locating surface, is fixedly fixed on substrate (4) upper by locating surface with glue, and locating surface can be plane.Optical fiber collimator (1) can directly be fixed on substrate (4).Substrate (4) can be glass plate, can be also the housing of Fibre Optical Sensor.The reflecting surface of front mirror (2) and back mirror (3) is all that curved surface or one of them are planes, and conventional curved surface is sphere.Can on front mirror (2), establish two breach, fix respectively two optical fiber collimators (1), receiving optical signals of a utilizing emitted light signal.Also can on front mirror (2), establish a breach, fix an optical fiber collimator (1) utilizing emitted light, on back mirror (3), also establish a breach, fix an optical fiber collimator (1) and receive light.Breach on front mirror (2) and back mirror (3) can be circular hole, installing optical fibres collimating apparatus (1).
In order to lengthen light path, this flat fiber gas sensor can be stacked up up and down or left and right get up to be used side by side, the output terminal of a sensor is connected to the input end connection of another sensor.
Accompanying drawing explanation
The schematic diagram that accompanying drawing 1 is the embodiment of the present invention.
The schematic diagram that accompanying drawing 2 superposes and uses for the present invention.
Embodiment
Below in conjunction with accompanying drawing, further describe embodiments of the invention.
Concrete scheme is: comprise optical fiber collimator (1), front mirror (2), back mirror (3), substrate (4).The shape of front mirror (2) and back mirror (3) is rectangular parallelepiped roughly the same, has spherical reflecting surface, and locating surface is plane, and with glue, fixes between substrate (4).Hole, front mirror (2) Shang Sheliangge garden, fixes respectively two optical fiber collimators (1).Substrate (4) is glass plate.
In order to lengthen light path, the use that stacks up of this flat fiber gas sensor, the output terminal of a sensor is connected to the input end of another sensor.
