Abstract
The complete procedure of measuring and correcting geometric deformations encountered with dynamic streak camera images in the picosecond range is presented and discussed. First, we describe the experimental setup derived from the well known spacing calibration grid method. The implemented measurement bench, adapted to time-resolved 1D imaging, notably exhibits a great accuracy and repeatability both in space and time thanks to a three-axis motorized translation stage and programmable delay lines. Second, we examine. image restoration by two different analytical transform means (local versus global): results and performances of both are compared. Then we deal with final image reconstruction performed by an original method of local C-2(2) spline interpolation.
