3D camera by projector flashes each different dot creating fast and slow electrical pulse it gives camera dots alternating with projector light dot

 3D camera by projector flashes each different dot creating fast and slow electrical pulse it gives camera dots alternating with projector light dot.First the projector dots light up at the same time and then turn off. The light activates the projector light dot at that location to light up the next time. Because the object is far and near, the light from each spot to each camera dot differs rapidly because the light path is far and near, but the light is very fast. The camera dots capture the light quickly and slowly in each place so the projector dots are lit fast and slow in each place.This is light more slowly so the camera dot captures slower and activates the projector dot again. light becomes slower and slower, so it becomes more and more slowly apart.This time creates different fast and slow electrical pulses.
