A laser detection system for determining distances and the rate of distance change with respect to a reference point (11) is disclosed. The system includes an infrared pulsing laser (13) in combination with infrared (IR) detector optics (18, 19) to detect (17) reflected (IR) pulses from a target. A timing device (39) is further included in the system to determine elapsed time between (IR) pulse generation and reflected pulse reception. A computer (40) controls laser operation and computes distance and rate of change of distance. The laser system may be used as a speed detector to determine the speed of a moving object or, in more rudimentary form, to measure distances from a reference point to an object or to measure one or more dimensions of an object. |
