Paper Abstract
The fluorescent reaction is that an organism or dye, excited by UV light (200-405 nm), emits a specific frequency of
light; the light is usually a visible or near infrared light (405-900 nm). During the UV light irradiation, the photosensitive
agent will be induced to start the photochemical reaction. In addition, the fluorescence image can be used for
fluorescence diagnosis and then photodynamic therapy can be given to dental diseases and skin cancer, which has
become a useful tool to provide scientific evidence in many biomedical researches. However, most of the methods on
acquiring fluorescence biology traces are still stay in primitive stage, catching by naked eyes and researcher's subjective
judgment. This article presents a portable camera to obtain the fluorescence image and to make up a deficit from
observer competence and subjective judgment. Furthermore, the portable camera offers the 375nm UV-LED exciting
light source for user to record fluorescence image and makes the recorded image become persuasive scientific evidence.
In addition, when the raising the rate between signal and noise, the signal processing module will not only amplify the
fluorescence signal up to 70 %, but also decrease the noise significantly from environmental light on bill and nude mouse
testing.
