Claims2
A mechanical mirror steering system comprising:
- a gimbal;
- a plane mirror pivotally mounted within the gimbal, a means for steering said plane mirror affixed to one side of the plane mirror and extending normal to the plane thereof, a first bifurcated link connected to a first universal swivel joint at one end;
- an arm means connected to a pivot for rotation about a first axis, said arm means having a second universal swivel joint atone end;
- a second bifurcated link connected to said second joint on said arm means to universally swivel thereby, and a slider bearing connecting said first and second links at their bifurcated ends and receiving, in a sliding relationship, said means for steering the plane mirror, whereby as the mirror rotates about said first axis radiation striking the mirror at a point along said first axis will describe a circular arc on a plane perpendicular to said first axis.
