  • Optical ranging anti-collision technique and system
    Patent number: 4681431
    Abstract: A collision avoidance system for preventing collision between vehicles capable of moving along the same general path, which system includes a vehicle having a device for emitting optical pulses and another vehicle having a detector which uses an optical scanner defining a substantially triangular scan field. The detector responds to the emitted optical pulses and determines the range between the vehicles and the closing speed between them. An alarm system responds to the closing speed determination to permit evasive action to be taken when the closing speed exceeds a selected value.
