Abstract
Distant radiation sources are imaged using a collimator having a multiplicity of portions, the transmissivities of the portions to radiation reaching the collimator from a given source being different from portion-to-portion for a given orientation of the collimator; these transmissivities are varied over time, and radiation passing through each portion is detected for successive values of its transmissivity.
