ABSTRACT:
An exclusively digital timing engine that measures extremely short time intervals for use in time of flight systems such as laser range finding systems. This exclusively digital timing engine minimizes the use of high speed, high cost components by employing a novel time multiplexing scheme to execute each of the primary time of flight functions: frequency synthesis, range gating, and time of flight interval measurement. In addition, the timing engine incorporates a random time delay scheme which enhances the resolution of the time interval measurement.
