The ground-based experimental results of the incident angle dependence on the erosion rate of polyimide under hyperthermal atomic oxygen beam exposures are reported. A hyperthermal atomic oxygen beam was generated by a laser detonation-type atomic oxygen beam source. In-situ mass loss measurement was made during the atomic oxygen exposure using a quartz crystal microbalance. It was observed that the erosion rate of polymers was followed cosine function with respect to the incident angle of atomic oxygen. This experimental finding clearly indicates that the reaction yield of atomic oxygen with polymers is independent of the incident angle. As for the fluence monitoring material, erosion depth or mass loss of polyimide simply reflects the effective atomic oxygen fluence which is calculated by multiplying normal flux and cosine of the incident angle.
