  • Compact spherical diffraction limited telescope system for remote sensing in a satellite system
    Patent number: 10146044
    Abstract: In one embodiment, an optical system includes: a first lens configured to receive incoming light from an object; a first mirror comprising a central aperture, the first mirror configured to refract the light from the first lens, reflect the light, and refract the light reflected from the first mirror; a second mirror configured to receive the light from the first mirror, wherein the light is refracted towards a first surface of the second mirror where the light is reflected back and refracted upon exiting the second mirror; a negative corrector lens configured to refract the light from the second mirror through the central aperture of the first mirror; and a positive corrector lens configured to receive the light through the central aperture of the first mirror and refract the light to an imaging surface.
