Abstract
Abstract An optical scanner assembly comprising first scanning means (12-18) for scanning a scene (10) and second scanning (36-44) means for providing a visible representation of the scene. The first scanning means includes an intermediate optical assembly for defining an image pupil on the further reflector thereof. The second scanning means includes an intermediate optical assembly for defining a path for the emitted radiation between the first and further reflectors of the second scanning means. The intermediate optical assemblies of the first and second scanning means are arranged substantially concentric with respect to the image pupil defined on the further reflector (20) of the first scanning means.
