Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
The embodiment discloses a paper currency counterfeit identifying device with strong applicability, which comprises a lamp tube fixing frame 1, a plurality of light emitting diodes 3 fixed on the lamp tube fixing frame 1, a sensor fixing frame 2 and an information analysis processing module, and is characterized in that the light emitting diodes 3 are arranged in two groups in the width direction of the lamp tube fixing frame 1 and respectively comprise a transmission light group and a reflection light group which work alternately, the two groups of light emitting diodes 3 can respectively emit visible light and invisible light alternately, a convex lens 6 used for condensing and intensifying penetrating power of light is arranged between the light emitting diodes 3 of the transmission light group and paper currency, a group of photosensitive sensors 4 is fixedly arranged on the sensor fixing frame 2 right below the light emitting diodes 3 of the transmission light group and corresponds to the light emitting diodes 3 of the transmission light group, a concave lens 5 used for dispersing and enabling light to irradiate uniformly is arranged between the light emitting diodes 3 of the reflection light group and the paper currency, the lamp tube fixing frame 1 is also fixedly provided with a photosensitive sensor 4 for collecting reflected light signals of the reflected light group irradiated on the paper money.
The reflection light group is in a standby state when the transmission light group works, and the transmission light group is in a standby state when the reflection light group acts.
The arrangement positions and the curvature radius of the concave lens 5 and the convex lens 6 are calculated according to the image distance and the object distance.
