An adaptive method for automatic calibration of interpolation time interval digitizer with picosecond resolution

An adaptive method is presented for real-time calibration of an interpolation time-interval digitizer (TID) with picosecond resolution. Reduction of calibration uncertainty to the level of 3 ps (RMS) has been achieved. Experimental results and comparison with some existing methods for TID calibration are also presented. The adaptive method was developed to solve a calibration problem that emerged in the course of developing an advanced TID for a satellite laser ranging systems.<>
