Patent ID: 7214916

Claim:
Optical arrangement ( 2 ) for a homing head ( 16 ), for imaging an object scene onto a detector unit ( 4 ), comprising a control unit ( 24 ), a first optical unit ( 10 ) having two at least partially transparent optical elements ( 42 , 44 ), a second optical unit ( 14 ) and a beam deflecting unit ( 18 ), the first optical unit ( 10 ) directing radiation from at least two sections of the object scene onto the beam deflecting unit ( 18 ) in superposition, and the beam deflecting unit ( 18 ) selecting one of the sections and, in conjunction with the second optical unit ( 14 ), imaging the selected section on the detector unit ( 4 ), characterized by a micromechanical movement actuator ( 46 , 48 , 50 ), the optical elements being mounted movably relative to one another, and the control unit ( 24 ) driving the movement actuator ( 46 , 48 , 50 ) and additionally setting a spacing ( 62 ) between the optical elements.
