ABSTRACT:
A positionally adjustable mirror arrangement includes a holding member which is mounted on a support for pivoting about two mutually perpendicular axes. A plurality of circumferentially distributed coarse pivoting actuators pivotally displaces the holding member relative to the support about the two axes within a relatively large angular range. A mirror is mounted on the holding member for pivoting about two mutually perpendicular auxiliary axes. A plurality of circumferentially distributed fine pivoting actuators pivotally moves the mirror member relative to the holding member about the auxiliary axes within a relatively small angular range.
