Abstract:
1. An apparatus for fluorescence imaging of a target object that is normal or is diseased, comprising: means to illuminate the target object with light in a first excitation wavelength region to excite a first fluorescence emission, said first excitation wavelength region being selected to excite said first fluorescence emission at an intensity greater for the target object that is normal than for the target object that is diseased; means to acquire said first fluorescence emission; means to simultaneously illuminate said target object with light in a second excitation wavelength region to excite a second fluorescence emission, said second excitation wavelength region being selected to excite said second fluorescence emission at an intensity lower for the target object that is normal than an intensity for the target object that is diseased; and means to acquire said second fluorescence emission.
