Abstract
Apparatus for measuring the time delay between pulse signals, particularly in conjunction with electro-optical range finders. A coarse measurement counter counts the output of a reference oscillator, while a fine measurement interpolator determines the residual time at the start and finish of a measuring interval. Both residual times are successively determined by the same fine measurement interpolator. A delay circuit only supplies the pulse transmitter with the trigger signal when the interpolation for the start signal in the interpolator is ended. An adjustable series of test pulses is produces by a clock generator, in order to form the average value from such a series of measurements in a logic circuit. Preferably, the clock generator is synchronized with the reference oscillator, which ensures the formation of a mean value with a narrow range of errors.
