Plans for a 10-m Submillimeter-wave Telescope at the South Pole [PDF]
, 1998 A 10 meter diameter submillimeter-wave telescope has been proposed for the NSF Amundsen-Scott South Pole Station. Current evidence indicates that the South Pole is the best submillimeter-wave telescope site among all existing or proposed ground-based ...

Freeform Wide Field-of-View Spaceborne Imaging Telescope: From Design to Demonstrator
Sensors, 2022 Wide field-of-view imaging optics offer a huge potential for space-based Earth observation enabling the capture of global data. Reflective imaging telescopes are often favored, as they do not show chromatic aberrations and are less susceptible to ...

Hexapod Design For All-Sky Sidereal Tracking [PDF]
, 2016 In this paper we describe a hexapod-based telescope mount system intended to provide sidereal tracking for the Fly's Eye Camera project -- an upcoming moderate, 21"/pixel resolution all-sky survey. By exploiting such a kind of meter-sized telescope mount,
