Abstract
An apparatus for optical pointing is disclosed. The apparatus comprises a telescope, a transmission prism rotatably coupled to the telescope, and a rotatable mechanism operatively coupled to the telescope. The transmission prism is configured to rotate around a first rotation axis, and the rotatable mechanism is configured to rotate around a second rotation axis that is different than the first rotation axis.

An apparatus for optical pointing, the apparatus comprising:
- a telescope;
- a transmission prism rotatably coupled to the telescope, wherein the transmission prism is configured to rotate around a first rotation axis;
- a rotatable mechanism operatively coupled to the telescope, wherein the rotatable mechanism is configured to rotate around a second rotation axis that is different than the first rotation axis;
- and
- a set of mirrors comprising a primary mirror and a secondary mirror arranged within the telescope, and a folding mirror configured to provide a folded optical path for a light beam propagating through the telescope.
