Claim 4:
5. The optical detection system according to claim 1,
wherein, when the beam quantity adjuster is a spatial light modulator, the spatial light modulator is configured for allowing the laser beam to pass through or for reflecting the laser beam, thereby converting the laser beam into the at least two projection beams, and the spatial light modulator is configured for adjusting a position of the light spot of the projection beam;
wherein, when different positions of the active region of the same photodiode are excited by the projection beam so as to respectively generate a plurality of different electrical signals, the electrical detection module is configured for electrically contacting the photodiode so as to obtain a plurality of different electrical signals of the photodiode, thereby calculating an average current value of the photodiode or determining a maximum current position of the active region of the photodiode.
