Relates to apparatus incorporating a two-dimensional array of image sensing devices arranged in rows and columns onto which a two-dimensional pattern of radiation having rows and columns of elements is scanned in the column direction. For each scan of a row of elements of the pattern of radiation from row to row of the array of image sensing devices a plurality of transformed outputs are obtained, one for each row of the array. Video signals corresponding to the integrated values of the intensities of the elements of the pattern of radiation are obtained by obtaining the inverse transforms of the transformed outputs.
