This paper presents the Palsys multi-imaging system, the recent history of the development of the system, and its component instrumentation as well as basic theory and practices of operation. The Palsys consists of the Palflash Short Exposure Pulsed Flash Unit; the Palseq, a four channel delay generator; the Palstor Video/Computer Framestore; the video CCD camera; long distance microscope or other suitable lens; and the Pals Computer Software. The Palsys can measure speed, size, distance, and angles to a very close tolerance of particle sizes, down to 15 microns at speeds of 15 m/s. The modular design of the Palsys allows for extreme system flexibility to achieve the desired results. The Palflash has uses in spray atomization, ballistic, detonics, schlieren studies, shadowgraph, etc.
