Abstract
Reflective optical telescopes and method of observing a scene. One example of a reflective optical telescope includes a primary mirror positioned along a linear axis extending between an entrance aperture and an image plane, configured to receive optical radiation via the entrance aperture, a secondary mirror positioned along the linear axis and configured to receive the optical radiation from the primary mirror and to reflect the optical radiation in a direction of the primary mirror, wherein the optical radiation received by the primary mirror is unobscured by the secondary mirror, a tertiary mirror positioned along the linear axis and configured to receive the optical radiation from the secondary mirror and reflect the optical radiation in a direction of the primary mirror, and a quaternary mirror positioned along the linear axis, configured to receive the optical radiation from the tertiary mirror and reflect the optical radiation to the image plane.
