Abstract
A fluorescence imaging system including a light source, an optical system, camera and an excitation light filter, the optical system produces a non-uniform fluence excitation illumination beam for illuminating an object and promoting fluorescence emissions, the optical system is positioned between the light source and the object, the optical system modifies the non-uniform fluence illumination beam into a uniform fluence illumination beam and changes the divergence of the uniform fluence illumination beam, the camera has an array of pixels, the camera detects the fluorescence emissions and performs pixel intensity measurements for each of the pixels, the excitation light filter is positioned between the object and the camera and filters out the excitation illumination beam, such that the excitation illumination beam does not reach the camera.
