Abstract

A method for determining a flux of inspection radiation is provided, wherein the inspection radiation is emitted by a radiation source and transmitted through cargo, and wherein the flux of inspection radiation is incident on at least one array of detector cells. The detector cells are configured in a first plurality L forming rows of the array, each row of detector cells extending along a direction parallel to a depth direction of the array, the detector cells being further configured in a second plurality λ forming columns of the array, each column of detector cells extending along a direction parallel to a longitudinal direction of the array. The method includes obtaining signal data associated with each detector cell of the array, and determining the flux of the inspection radiation incident on row i, for each row i such as 1≤i≤L, based on the signal data for each detector cell.
