Digital imaging holography and pyrometry of aluminum drop combustion in solid propellant plumes

Chen, Yi; Guildenbecher, Daniel R.; Hoffmeister, Kathryn N.; Sojka, Paul E.

Aluminized propellants produce molten particulates of variable size and temperature. In this work, sizes and three-dimensional positions are determined using digital in-line holography with a pulsed laser. Simultaneously, particle temperatures are measured using two-color pyrometry.
