A device and a method for detecting reflected and/or emitted light of an object (1) are proposed having at least one illumination device (2) illuminating the object (1) with pulsed light, and having at least one sensor (4, 6) capturing the light reflected and/or emitted by the object (1), and having a transport device transporting the object relative to the illumination device (2) and past the sensor 4, 6) in the direction of transport, and having a power supply (16, 17, 18, 19, 20, 21, 22) for the illumination device (2) providing the illumination device (2) with a current that is a periodic function over time, wherein a period comprises at least two current pulses (23, 24) of different magnitudes.
