Optical arrangement for a homing head with movable optical elements
Abstract:
An optical arrangement (2) for a homing head (16), for the purpose of imaging an object scene onto a detector unit (4), including a control unit (24), a first optical unit (10) having two at least partially transparent optical elements, in particular prisms (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 a superimposed fashion, 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).
