title: Resistance of holograms made in Polaroid DMP128 photopolymer to ionizing radiation damage.
abstract: Because of their light weight and general wave-front-transforming ability, holograms appear potentially useful as beam correctors and collimators for diode-laser arrays in intersatellite optical data links. However, to survive in space a hologram must withstand damage from electrons and protons trapped in the Van Allen belts. We have found that holograms made with Polaroid DMP128 photopolymer on Suprasil-2 can withstand 63-MeV protons up to a total dose of 2 Mrad (Si) and withstand (60)Co gamma rays up to a total dose of 2 Mrad (Si) without loss of diffraction efficiency. It appears that these holograms are sufficiently radiation hard for space application.
