Abstract:
1. A device for inspecting an object, said device comprising: at least one illumination device that illuminates the object with pulsed light, a transport device that transports the object relative to the illumination device, a power supply for the illumination device that provides the illumination device with a current that is a periodic function over time, wherein a period comprises at least two current pulses with different magnitudes, at least one first sensor for capturing light reflected from the object, and at least one second sensor for capturing light emitted from the object through fluorescence or phosphorescence, the first sensor and the second sensor being located at different positions, at least one of the first or second sensors has a saturation limit: and wherein outputs from the first and second sensors are configured to recognize, inspect, verify and test whether the object is genuine; and wherein an output from a sensor when sensing light from the smaller magnitude pulse is used when the saturation limit for the sensor is reached when sensing light from the larger magnitude pulse.
