  • Method and apparatus for asynchronous time measurement
    Patent number: 4908784
    Abstract: The present invention relates to time measurement apparatus and method for measuring, with picosecond precision, intervals between single edged events, where each measured interval comprises the summation of a rough clock count and fine or calibrated vernier counts of measured fractional clock periods before and after each START and STOP event selected from a calibrated vernier memory. The calibrated vernier memory takes the form of a table of linear voltage versus time developed using pseudo-random generated measurement events of random duration and random separation.
