ABSTRACT:
Apparatus is disclosed for digitally deflecting a line-of-sight (LOS) axis of an energy beam, or an optical LOS axis of an optical train, in each of two mutually orthogonal directions of deflective sweep. The apparatus utilizes a series of mirrors, each of which is independently pivotable about two orthogonally related linear pivot axes. Each of the mirrors doubles the deflection movement of the preceding mirror so that binary values of deflection of the LOS are generated by selective control of the mirrors of the series. Positioning of each mirror is provided by a "four position-two orthogonal axis actuator" which forcibly drives the mirror between any one to any other of four positions consisting of combinations of two pivotal deflection positions about each of two mutually orthogonal linear pivot axes.
