ABSTRACT:
An achromatic scanning system 25 subjects an incoming beam of light to reflection off four successive mirrors (35a, 42a, 42b, 35b). The mirrors at the input and output are preferably plane mirrors (35a-b) and are referred to as the scanning mirrors. They are movable and provide the desired beam displacement when appropriately driven. They face away generally from each other and are rotatable about respective axes. Each axis lies in the plane of its respective mirror and the two axes are non-parallel (preferably perpendicular) to each other. The two intermediate mirrors are concave mirrors (42a-b) that face each other and define an afocal assembly that transfers the light reflected from the first scanning mirror (35a) to the second scanning mirror (35b).
