We performed miniature flyer impact experiments to investigate the relationship between the apparent (u{sub a}) and actual (u{sub A}) particle velocities measured by a velocity interferometer in single-crystal lithium fluoride (LiF) that was shock-compressed along the [100] axis. The miniature flyer was accelerated to velocities in the range 652.5-1937.6 m/s by a tabletop pulsed laser. An empirical relationship of u{sub a}= (1.2749 {+-} 0.0102)u{sub A} was obtained. The obtained relationship agreed well with the results of a previous study within the experimental errors and its uncertainty was less than {+-}1%. This result indicates that the present experimental technique is effective for measuring the relationship between u{sub a} and u{sub A} of shocked transparent materials with a comparable accuracy to conventional methods.
