Abstract
A process for generating distance images operates by the emission of light pulses and the synchronized time-delayed reception of the reflected light pulses on an image receiving unit with a shutter device connected in front of it. During the reception of a reflected light pulse, the transparency of the shutter device passes through a given time-dependent function and in this manner at least two such modulated reflection images are generated while different transparency functions are used. A color is assigned to each of these images, and the colored images are superimposed to form a false-color-coded distance image.
