摘要：
The precision of the pulsed laser ranging system was decided by the precision of the time interval measurement. Therefore, a high resolution time interval measurement module was developed. The module is based on the special time-to-digital conversion chip which adopts the delay line interpolation method. The maximum measuring time of the module is 200 ms, and the maximum time resolution is 125 ps, of which the corresponding distance resolution is 18.75 mm. The module is especially suit for the large distance measurement. The hardware and the software of the module as well as the testing results are also presented.
