Abstract

The knife-edges of baffle vanes can specularly reflect out-of-field optical radiation in such a manner that it can scatter from the primary mirror into the field-of-view thereby degrading the performance of the optical sensor. Decreasing the radius of curvature of the knife-edges is an obvious technique for minimizing this effect. However, the x-ray hardness of the baffle vanes is negatively impacted by decreasing the radius of curvature of the knife-edges. Thus, there are tradeoff considerations on the radius of curvature of the baffle knife-edges. This results in a need for an accurate requirement on the radius of curvature of the baffle knife-edges. The Physitron-developed computer simulation KNIFEDGE is used to compute the required baffle knife-edge radius for exoatmospheric interceptors and surveillance sensors. A scaling expression is then derived that allows the results to be scaled to sensor designs other than those considered in the investigation.
