PURPOSE: A fluorescence lidar optical receiving system and a fluorescent material detecting apparatus and method thereof are provided to distinguish the kind of a fluorescent material from relatively small waves by extracting only important wave vectors. CONSTITUTION: A fluorescence lidar optical receiving system comprises a concave mirror(206), a first diffraction plate(207), a second diffraction plate(208), a lens system(209), and a sensor(211). The concave mirror changes fluorescent light entering through a telescope into collimated light. The first diffraction plate diffracts a light of first wave length included in the collimated light to a first direction. The second diffraction plate diffracts the light of a second wave length different from the first wave length to a second direction meeting with the first direction at the right angle. The lens system images the lights diffracted to the first and the second direction on a focal plane. The sensor selects desired wavelengths from the imaged lights and changes the intensity of the selected wavelength lights into electrical intensity.
