A system for determining a distance to an object including a solid-state light source for projecting a pattern of discrete spots of laser light towards the object in a sequence of pulses; a detector having a plurality of picture elements, for detecting light representing the pattern of discrete spots as reflected by the object in synchronization with the pulses; and a processor to calculate the distance to the object as a function of exposure values generated by the picture elements. The picture elements are configured to generate exposure values by accumulating, for each pulse of the sequence, a first amount of electrical charge representative of a first amount of light reflected by the object during a first time window and a second electrical charge representative of a second amount of light reflected by the object during a second time window, the second time window occurring after the first time window.
