Abstract:

HETERODYNE HOLOGRAPHIC INTERFEROMETRY AND TIME-AVERAGE HOLOGRAPHY WITH A FREQUENCY SHIFTED BEAM HAVE BEEN PROPOSED FOR USE IN THE MEASUREMENT AND VISUALIZATION OF INTERNAL TRANSONIC FLOWS. A LONG PULSE FLASHLAMP EXCITED DYE LASER HAS BEEN SHOWN TO PRODUCE OVER 50 MILLIJOULES PER PULSE FOR OVER 50 MICROSECONDS TO PRODUCE FRINGES WITH A COHERENCE LENGTH IN THE ORDER OF 30 CM. ALTHOUGH TEMPORAL COHERENCE IS GOOD, SPATIAL COHERENCE OVER THE LASER BEAM APERTURE IS POOR. A PLAN TO INCREASE SPATIAL COHERENCE BY IMPROVING THELASER RESONATOR DESIGN IS PROPOSED. WITH THIS CHANGE THE LONG PULSE FLASHLAMP LASER WILL BE USEFUL FOR TIME-AVERAGE HOLOGRAPHY.
