A Simple optical layout of fluorescence imaging system: (a1), optical frequency double system; (a2), lens; (a3), liquid-nitrogen cooled CCD-array spectrophotometer. (b) and (c) Spectroscopic imaging of (b) QDs-tagged tumor tissue and (c) normal tissue. (d) and (e) Emission spectrum of (d) QDs-tagged tumor tissue and (e) normal tissue. All the images and the spectrums were captured from a nude mouse with the same exposure time [68].
