Currency processing systems, coin processing machines, and methods of imaging coins are presented herein. A currency processing system is disclosed which includes a housing with an input area for receiving coins and receptacles for stowing processed coins. A disk-type coin processing unit is coupled to the coin input area and coin receptacles. The coin processing unit includes a rotatable disk for imparting motion to coins, and a sorting head adjacent the rotatable disk with shaped regions for guiding moving coins to exit channels through which the coins are discharged to the coin receptacles. A sensor arrangement mounted adjacent the rotatable disk includes one light emitting device for emitting light onto a coin surface at near-normal incidence. A photodetector senses light reflected off the coin surface and outputs a coin-image signal for processing the coin.
1. A high-speed currency processing system comprising: a housing with a coin input area configured to receive a batch of coins;one or more coin receptacles operatively coupled to the housing;a coin processing unit operatively coupled to the coin input area and the one or more coin receptacles, the c
1. A high-speed currency processing system comprising: a housing with a coin input area configured to receive a batch of coins;one or more coin receptacles operatively coupled to the housing;a coin processing unit operatively coupled to the coin input area and the one or more coin receptacles, the coin processing unit being configured to process a plurality of the coins and discharge the processed coins to the one or more coin receptacles; anda sensor arrangement operatively coupled to the coin processing unit, the sensor arrangement including a photodetector and first and second light emitting devices, the first light emitting device being configured to emit light onto a surface of a passing coin at normal or near-normal incidence, the second light emitting device being configured to emit light onto the surface of the passing coin at high-angle incidence, and the photodetector being configured to sense light reflected off the surface of the passing coin and output a signal indicative of coin image information for processing the coin;wherein the coins pass the sensor arrangement and the sensor arrangement outputs a signal indicative of coin image information at a rate of at least 2000 coins per minute;wherein the photodetector includes a linear array of photosensors with a normal incidence with the surface of the passing coin. 2. The currency processing system of claim 1, further comprising a light diffusing element operable to diffuse high-angle incidence light emitted by the second light emitting device. 3. The currency processing system of claim 1, further comprising a cylindrical lens and a light scattering element operable to scatter high-angle incidence light emitted by the second light emitting device. 4. The currency processing system of claim 1, further comprising a processor operatively coupled to the sensor arrangement to receive the coin image information signals and determine therefrom whether the passing coin is valid or invalid. 5. The currency processing system of claim 1, further comprising a processor operatively coupled to the sensor arrangement to receive the coin image information signals and determine therefrom a denomination, a fitness, or an authenticity, or any combination thereof, of the passing coin. 6. The currency processing system of claim 1, wherein the sensor arrangement is configured to sense all or substantially all of a top surface of the passing coin. 7. The currency processing system of claim 1, further comprising a lens array between the photodetector and the passing coin. 8.
