| The UV sensor is manufactured
with UV-sensitive optical fiber as a sensitive element. This
UV-sensitive optical fiber can transform UV light into visible light.
When UV irradiate UV-sensitive optical fiber from its side face, the
visible fluorescence will be appeared from its end face. Then we
transform the optical signal into electrical signal through electric
eye. The electrical signal amplification system is designed in
accordance with the characteristic of the UV light intensity. It can
effectively remove the interference of the non-UV light of the
sunshine and other light sources. This technique has obtained the
nation invention patent right in 1996. This sensor can be used for the
measurement of UV light intensity in the fields of medicine, hygiene,
food, photochemistry, UV fluorescence analysis, etc. It has many
advantages, such as high sensitivity, small volume, high accuracy and
reliability. |
