OPTICAL IMAGE SYSTEM USED MULTI LIGHT SOURCE AND THEREFORE METHOD

Disclosed is an optical imaging system capable of improving reliability and accuracy of diagnosis and effectively observing a lesion. The optical imaging system according to the present invention comprises: a first light source generator which generates a first light source which is modulated to a first frequency; a second light source generator which generates a second light source which is modulated to a second frequency; and a single camera which simultaneously detects complex emitting light sources which are emitted after the first and second light sources are irradiated on an object and output complex image detecting signals. Furthermore, the optical imaging system comprises an image processing unit which processes the complex image detecting signals to obtain a first image to express the shape of the object and a second image to express a desired target part of the object. According to the present invention, the optical imaging system is able to simultaneously obtain fluorescent signals which are hard to be obtained in a general color image, and accurately map the lesion, thereby providing information including a location, a size and a transfer degree of the lesion.
