The Time-Shift Technique for Measurement of Size and Velocity of
... The time-shift technique is used here in a somewhat modified form. This technique was first introduced by Semidetnov (1985) [3] and is further developed in Damaschke et al (2002) and Albrecht et al (2003). It is realized by creating an illuminated volume considerably smaller than the size of the par ...
