Abstract : This report describes the design and synthesis of a hologram camera and reconstruction system for measuring particle sizes in the 3 to 1000-micron range in explosively generated aerosols. The objective was to measure a volume of high velocity particles in situ. Theoretical resolution requirements and design details concerning 10 camera configurations with magnifications from 1 to 25X, capable of resolving particles from 3.5 to 1000 microns, are discussed. The design of a laser collimator to provide a 20 nsec illumination source is described. Aerosol sample volumes from 6.75 cu mm to 256 cu cm were reconstructed from individual photographs. Recommendations for further refinement of this working system are included.
