Stacked sheets of polyethylene terephthalate andpolystyrene provide a means
for recovering projectiles travelling at hypervelocities. The transparency of these
multiple diaphragms is utilized so that light generated from hypervelocity impacts
can be studied.
A method for gathering visible as well as ultraviolet light from less
transparent polymer foams has been confirmed. Distinct spectral characteristics
as well as a blackbody temperature can now be used as tools for characterizing the
response of polymer foams to hypervelocity impact.
The identification of newly discovered excited atomic transitions from the
incident projectile suggests a method for observing the thermal history of the
projectile as it progresses through the capture medium. / Graduation date: 1991
