System.
(2) FDM system of the present utility model, through system combination, by the data analysiss of each light path out, can obtain
The details of more fluorescence is it is seen that the optical signal that more branches away.
(3) this utility model adopts sensitivity higher, and speed faster optical power detector APD substitutes CCD, uses optical filter
Group replaces grating, makes the selection of wavelength of fluorescence more flexible, solves the problems, such as fluorescence cross simultaneously, can obtain more fluorescence letters
