A line scanning system wherein a multiple element detector array receives radiation from a scanning rotator having mirror surfaces inclined relative to the axis of rotation. Image distorting effects due to inequality of lines which are concurrently scanned, are offset by individually delaying the electric signals which are individually derived from the detector elements; these delays are related to the instantaneous scanning angle. The electrical signals, thus compensated are converted into a corresponding number of separate light beams which are individually applied to corresponding light inputs of a multiple input optical system comprising a configuration of prisms, which are effective to combine the separate input beams into a single output beam composed of coaxially disposed, rotationally symmetric sub-beams.
