The utility model relates to a banknote detection area specifically is a many spectral image acquisition and analysis processing system of high -speed high resolution of bank note. The both sides of transmitting the position at the bank note set up RGB light source reflection image sensor and/or IR infrared light source reflection image sensor respectively, the both sides of transmitting the position at the bank note set up uv light source reflection image sensor respectively, the one side of transmitting the position at the bank note sets up the infrared emission light source, and the opposite side that transmits the position at the bank note sets up infrared receiving sensor, and infrared emission light source, infrared receiving sensor set up relatively. The utility model discloses the problem that in the time of can solving among prior art paper currency image acquisition low -speed, low resolution, light source are single etc. The serial number of discernment paper currency, face value, towards, new and old degree pollutions, incomplete degree, plain boiled water print, falun gong coin scheduling problem improves a lot.
