Abstract
Shadowgraphic holography allows imaging of small particles over a 180 degree field of view and with a large depth of field. The cylindrical holography technique developed by Hough and Gustafson has been modified to allow holograms of small hypervelocity impact generated simulated space debris particles to be successfully made by using a subnanosecond laser pulse length. The use of very short (135 ps) laser pulses with a corresponding short coherence length (4 cm) frees the motion of small high speed particles. With this system, shadowgraphic holograms of aluminum projectiles impacting aluminum and graphic epoxy plates have been achieved at hypervelocity. Results of these tests as well as low speed proof of concept tests are presented.
