Abstract

The use of collimators and shields for measurements and imaging with X- and γ -rays requires a well-defined collimation for the pixels and well-determined formula for the effect of the collimators. We analyze the geometric effects of tubular and pinhole collimators and the effects of curved shields for the case of omni-directional fluxes. These effects can affect measurements of X- and γ-rays as well as UV rays behind the shield and collimators. On the other hand, such effects can be used to enhance the capability of multi-spectral sensors by using appropriate covers in front of them.
