【Abstract】 A opto-electronics sensor for detecting the infrared up-conversion materials on bank note has been designed. In the text, the principle, the structure and the signal processing circuit of the opto-electronics sensor is introduced. The senor has many advantages, such as small cubage, high antijamming ability, etc. It also provide a easy way to use infrared up-conversion materials in anti-counterfeiting technology. This sensor can be easily and widely used in detecting banknotes.更多还原
