Study of the Double Stretch Interpolation Technique for Time Interval Measurement

This paper proposed a double stretch interpolation method based on the charge and discharge principles of the capacitors, and studied the working principles of the double stretch time measurement interpolator and its error analysis. The double stretch interpolation method is able to greatly increase the time measurement resolution and reduce the interpolation time comparing with the single stretch interpolation technique. Therefore, the conflict between the high time measurement resolution and rapid measurement speed of the single stretch interpolation method is solved efficiently.
