Abstract
An apparatus for selective multi-directional illumination of an object, particularly for selective multi-directional imaging of an object, comprises a central mirror selectively rotatable about a central axis for reflecting light arriving along the central axis in selected directions radial to the axis. A plurality of differently tilted mirrors are mounted on an annular member selectively rotatable around the central axis for disposing selected ones of the tilted mirrors in the path of light from the central mirror. The tilted mirrors reflect light onto an object at a direction determined by the angular position of the central mirror and at an angle of elevation determined by the selected tilted mirror. Light reflected from the illuminated object reaches an imaging device along a path retracing the illuminating light whereby the direction of viewing of the imaged object corresponds to the direction of illumination of the object.
