が望まれていた。Conventional techniques for detecting ultraviolet rays include a method using an element that converts ultraviolet rays into electrical energy, a method using a chemical reaction caused by external rays, and a method using a substance that emits light when exposed to ultraviolet rays. A signal transduction system is required to detect ultraviolet light at a distance. Furthermore, when using chemical reactions caused by ultraviolet rays, there is also a change over time in which the chemical substances gradually break down due to the strong energy of the ultraviolet rays. Therefore, it has been desired to develop an ultraviolet detection method that integrates an ultraviolet detection system and a signal transmission system and is highly durable.

能とした紫外線検出方法を得ることができる。[Example] The present invention will be described below based on the illustrated example. FIG. 1 shows an embodiment of the invention. In this embodiment, the ultraviolet ray 1 is passed through a filter 2, the ultraviolet 1 that has passed is incident on a first optical fiber 3 containing Ge, and the first optical fiber 3 converts the ultraviolet ray 1 into a first visible light. After converting this first visible light into a second visible light 5 having a longer wavelength using a fluorescent substance 4, this second visible light 5 is incident and propagated into a second optical fiber 6 to emit ultraviolet light. 1i11 is now detected. In addition, in the same figure, 7 is a connection part. By doing this, the ultraviolet rays 1 are filtered through the filter 2.
．． first optical fiber containing GO; 3° fluorescent material; 4. Since the ultraviolet rays are detected via the second optical fiber 6, it is possible to obtain an ultraviolet detection method in which the ultraviolet detection system and the signal transmission system are integrated and the durability can be improved.

より長波長の第２の可視光５に変換づる。This filter 2 is for excluding visible light. (Ultraviolet and visible light is generated in the first optical fiber 3 including 3e. First light)? Since the transmission zero loss of the optical fiber 3 is larger for the ultraviolet ray 1 than for the first visible light, as the first optical fiber 3 becomes longer, the incident ultraviolet ray 1 is attenuated and the first visible light is propagated. This first visible light reaches the end of the first optical fiber 3, but since the wavelength of 0°42 μm has poor sensitivity to the naked eye, it is placed at the end of the first optical fiber 3 to make it easier to see. The attached fluorescent material 4 converts the orange-white or red visible light into second visible light 5 having a longer wavelength than the first visible light.

５が肉眼に見易く出射される。If the second visible light 5 having a longer wavelength than the first visible light generated by this fluorescence '#1QII is further transmitted through the second optical fiber 6, it will be transmitted from the second optical fiber 6 to the second visible light. Light 5 is emitted so that it is easily visible to the naked eye.

外線検出方法が得られる。In this way, according to this embodiment, the ultraviolet detection system and the (H9-3! system) are integrated by utilizing the fact that the first optical fiber 3 including Qc emits visible light when irradiated with ultraviolet light. Furthermore, by using the fluorescent material 4, the ultraviolet rays 1 can be detected in a form that is easily visible to the naked eye, so a simple and durable ultraviolet ray detection method can be obtained.
