Wide field multi-mode telescope

摘要

A telescope with a spherical primary mirror and movable lightweight secondary assembly which includes an optical, imaging component and at least one location component both of which components are attached to a pivot arm. The location component can be a microwave, radio frequency or acoustic location component. The optical component of this secondary assembly reflects a portion of focused light radiation from the primary mirror back to the primary mirror and thence through a hole in the secondary mirror to a coude' optics device at the center of curvature of the primary mirror. The coude' optics device in turn reflects the focused light radiation to an imaging detector housed in the outer structure of the telescope. A preferred embodiment of the present invention combines all three of these location systems with the optical imaging component.
