Abstract:

Alumina particles ranging from minor dimension 25 microns to major dimension 185 microns are given 20-120 ms velocities via a carrier gas through a 500 microns nozzle. Off-axis image plane holograms are constructed of the dust. Resolution to 6 to 10 microns is achieved and image subtraction via a Pockels cell external to the laser cavity is employed to restore contrast loss in double exposures. Particle velocities are measured in double exposures. Author
