Abstract
A telescope includes a primary mirror, a secondary mirror configured to move along a first axis, and a tertiary mirror configured to move along a second axis. The secondary and tertiary mirrors are configured to move along respective axes in a synchronized manner to focus a beam of electromagnetic radiation from the primary mirror. The telescope further may include an anamorphic deformable mirror configured to achieve wavefront control and correction of optical aberrations. The telescope further may include a first linear actuator configured to move the secondary mirror along the first axis and a second linear actuator configured to move the tertiary mirror along the second axis.

A telescope comprising:
- a primary mirror;
- a secondary mirror configured to move along a first axis;
- a first actuator configured to move the secondary mirror along the first axis;
- a tertiary mirror configured to move along a second axis;
- and
- a second actuator configured to move the tertiary mirror along the second axis,
- wherein the first actuator and the second actuator to move the secondary mirror and the tertiary mirror along respective axes in a synchronized manner to focus electromagnetic radiation from the primary mirror, wherein the telescope is configured to limit root mean square wavefront on-axis error below 0.15 waves @ 1.055 um over entire 0.3 km to infinity range.

A method of directing electromagnetic radiation along an optical path of a telescope, the method comprising:
- directing electromagnetic radiation to a primary mirror configured to receive and reflect electromagnetic radiation along the optical path;
- directing electromagnetic radiation from the primary mirror to a secondary mirror configured to receive electromagnetic radiation from the primary mirror and to reflect electromagnetic radiation along the optical path;
- directing electromagnetic radiation from the secondary mirror to a tertiary mirror configured to receive electromagnetic radiation from the secondary mirror and to reflect electromagnetic radiation along the optical path;
- moving the secondary mirror along a first axis with a first actuator;
- and
- moving the tertiary mirror along a second axis with a second actuator,
- wherein the first actuator and the second actuator are configured to move the secondary mirror and the tertiary mirror along respective axes in a synchronized manner to focus electromagnetic radiation from the primary mirror, wherein the telescope is configured to limit root mean square wavefront on-axis error below 0.15 waves @ 1.055 um over entire 0.3 km to infinity range.
