Abstract
The invention pertains to a system for determining a distance, comprising: a light source for projecting a pattern of discrete spots of laser light towards the object in a sequence of pulses; a detector comprising picture elements, for detecting light representing the pattern as reflected by the object in synchronization with the sequence of pulses; and processing means to calculate the distance to the object as a function of exposure values generated by said picture elements. The picture elements generate the exposure values by accumulating a first amount of electrical charge representative of a first amount of light reflected during a first time window and a second electrical charge representative of a second amount of light reflected during a second time window, the second time window occurring after the first time window. The picture elements comprise at least two sets of charge storage wells, each configured as a cascade.
