Abstract
In an opto-mechanical scanner combining scanning and ranging functions the scanning beam, obtained from line-scanning means and frame-scanning means, and the ranging beam converge on a scanning detector array and a ranging detector, respectively. In accordance with the invention, the scanning beams and the ranging beams traverse an arrangement of fixed optical elements which are arranged to ensure that the beam each follow two different optical paths such that the ranging beam bypasses the line-scanning means. This ensures that the ranging beam has a fixed spatial orientation which is independent of the line-scanning means.
