An imaging system is described which includes a radiation source outputting radiation incident on a scene. The radiation is pulsed and the reflected radiation is detected by a detector array and a resulting signal output by a read out circuit. The signal output is characteristic of the scene on which the radiation is incident. The output signal is combined over a number of pulses, the averaging being carried out on-chip and within the detector circuitry. The radiation source may be a semiconductor diode source amplified with a doped fibre amplifier.
