A collision warning system includes pairs of optical sensors integral to a moving vehicle. Each of the optical sensors of the pairs of said sensors is enabled for the detection of visible light magnitudes and infrared light magnitudes in the external vicinity of the vehicle, and for creating corresponding electrical signals. Temporal changes in the magnitudes of the electrical signals and a probability of a collision with an object external to the vehicle, are determined and a warning signal is generated when collision is possible. Warning information is presented to alert a vehicle operator as to the possible collision. A reference sensor and an object sensor, are enabled for generating the related electrical signals. The reference and object sensors are positioned in such proximity as to determine when a collision object has entered a sensing field of view.
