Abstract
The utility model provides an optical fiber ultraviolet sensing device, wherein, one end of the optical fiber is coated by fluorescent powder. When the ultraviolet irradiates the fluorescent powder, the fluorescent powder emits visible light which is transmitted from one end of the optical fiber to the other end of the optical fiber. The higher the intensity of the ultraviolet is, the stronger the brightness of visible light emitted by the fluorescent powder is, and the stronger the brightness of the visible light transmitted to the other end of the optical fiber is. Thus, the intensity of the ultraviolet can be determined by measuring the brightness of the visible light transmitted to the other end of the optical fiber, thereby achieving the aim of measuring the intensity of the ultraviolet.
Description
Technical field
The utility model relates to a kind of ultraviolet sensing device, particularly a kind of optical fiber ultraviolet ray sensing device.
Background technology
At present, all adopt silicon photovoltaic effect device to carry out to the test of uitraviolet intensity.This class installation cost is higher, need the input front end of the very high amplifier of very accurate while enlargement factor as secondary instrument simultaneously.Also have the volume of this class device also bigger, be unfavorable in narrow environment, using.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned shortcoming, a kind of simple in structure, long service life is provided, does not need the very high amplifier of very accurate while enlargement factor as the input front end of secondary instrument and the optical fiber ultraviolet ray sensing device that can use in narrow environment.
The technical scheme that the utility model optical fiber ultraviolet ray sensing device adopts is: fluorescent powder is coated in of optical fiber.Fluorescent powder can send visible light when ultraviolet ray shines on the fluorescent powder, and visible light can be from a biography of optical fiber to the other end.The visible light brightness that the high more fluorescent powder of ultraviolet intensity sends is strong more, and the visible light brightness of passing to the optical fiber other end is also strong more.Just can judge ultraviolet intensity so pass to the visible light brightness of optical fiber other end by measurement, reach the purpose of measuring uitraviolet intensity.
The beneficial effects of the utility model are: simple in structure, make long service life easily.The secondary instrument circuit is supporting easily, measures accurately.Simply, safety, reliable.Partly do not have with luminescence-utraviolet and to electrically contact.
