Claim One:
1. An optical imaging system using multiple light sources, comprising: a first light source generating a first light modulated with a first frequency; a second light source generating a second light modulated with a second frequency; a camera simultaneously detecting multiple lights output from an object after the first and second lights are illuminated on the object and outputting multiple image detecting signals the multiple image detecting signals including a first reflection light of the first light that is reflected on a surface of the object, a second reflection light of the second light that is reflected on said surface of the object, and a third reflection light of the second light that is reflected on a desired target portion inside the object; a filter for removing the second reflection light from the multiple image detecting signals after detection by the camera; and an image processing unit processing the multiple image detecting signals without the removed second reflection light to obtain a first image representing a shape of the object from the first reflection light and a second image representing the desired target portion inside the object from the third reflection signal.
