| Abstract: | A digital speckle pulsed multi-exposure photographic technique has been proposed instead of the traditional technique using photographic plates for the display of transient motion paths. The principle of the proposed method is described in detail in terms of the Young' S fringe model. Experimental result for the transient lateral motion and the tilt of the measured body is presented. The factors which affect the measuring results have been analysed. |
