Control System Modeling for the Thirty Meter Telescope Primary Mirror
The Thirty Meter Telescope primary mirror is composed of 492 segments that are controlled to high precision in the presence of wind and vibration disturbances, despite the interaction with structural dynamics. The higher bandwidth and larger number of segments compared with the Keck telescopes requires greater attention to modeling to ensure success. We focus here on the development and validat...
متن کاملServo design and analysis for the Thirty Meter Telescope primary mirror actuators
The Thirty Meter Telescope has 492 primary mirror segments, each incorporated into a Primary Segment Assembly (PSA), each of which in turn has three actuators that control piston, tip, and tilt, for a total of 1476 actuators. Each actuator has a servo loop that controls small motions (nanometers) and large motions (millimeters). Candidate actuators were designed and tested that fall into the ca...
متن کاملDesign study of 8 meter monolithic mirror UV/optical space telescope
The planned Ares V launch vehicle with its 10 meter fairing shroud and 55,000 kg capacity to the Sun Earth L2 point enables entirely new classes of space telescopes. NASA MSFC has conducted a preliminary study that demonstrates the feasibility of launching a 6 to 8 meter class monolithic primary mirror telescope to Sun-Earth L2 using an Ares V. Specific technical areas studied included optical ...
متن کاملDesign of a Prototype Primary Mirror Segment Positioning Actuator for the Thirty Meter Telescope
The Thirty Meter Telescope (TMT) is a collaborative project between the California Institute of Technology (CIT), the University of California (UC), the Association of Universities for Research in Astronomy (AURA), and the Association of Canadian Universities for Research in Astronomy (ACURA). In order for the Thirty Meter Telescope (TMT) to achieve the required optical performance, each of its...
متن کاملLarge-Aperture Mirror Array (LAMA) - conceptual design for a distributed-aperture 42-meter telescope
We propose a high-density coherent array of eighteen 10-meter liquid-mirror telescopes. Each telescope is equipped with a reflective corrector system that enables it to point and track within an eight-degree diameter accessible field of view centered on the zenith. Equipped with adaptive optics, each telescope will deliver a diffraction-limited beam to a common focal plane. There, a dichroic op...
