The GMT adaptive secondary mirror (ASM) is based on a "segmented" concept following the primary segment layout: seven 1.05m diameter circular, independent adaptive mirrors are fed by the primaries and focus to the main telescope focal stations.

Phasing metrology system for the GMT
SPIE Proceedings, 2012The Giant Magellan Telescope (GMT) is a 25.4 m diameter ground-based segmented Gregorian telescope, composed of 7 8.4 meter diameter primary mirror segments, and 7 1 meter diameter adaptive secondary mirror segments. Co-phasing of the integrated optical system will be partially achieved by making real-time measurements of the wavefront of an offaxis

On the solution of periodical structures with the GMT
International Symposium on Antennas and Propagation Society, Merging Technologies for the 90's, 1990The state of the art of the MMP (multiple multipole) codes is examined, and different possible combinations with other methods are described. The basic principles of the MMP codes and of the combination with the Floquet theory are considered, and an overview of the analytical basis path of resolution is given.

Giant Magellan Telescope (GMT)
SPIE Proceedings, 2004The partners in the Magellan Telescopes have formed a core group to collaborate in a project whose goal is the design and construction of one or more 20-meter class telescopes. The conceptual design for the unit telescope is being developed and the status of the work is described here. The design is based on a segmented primary mirror consisting of six

This chapter begins with an overview of the variety of methods and techniques used to choose discrete pole locations in the family of Generalized Multipole Techniques (GMT). The heuristic rules and guidelines that are described are often quite successful. In addition, studies of the performance of GMT methods for canonical problems are reviewed. It has

A 3D metrology system for the GMT
SPIE Proceedings, 2016The Giant Magellan Telescope (GMT) 1 is a 25 m telescope composed of seven 8.4 m “unit telescopes”, on a common mount. Each primary and conjugated secondary mirror segment will feed a common instrument interface, their focal planes co-aligned and co-phased.

GMT software and controls overview
SPIE Proceedings, 2012The Giant Magellan Telescope Organization is designing and building a ground-based 25-meter extremely large telescope. This project represents a significant increase in complexity and performance requirements over 8-10 meter class telescope control systems.

Development plan of Korea for the GMT
SPIE Proceedings, 2010Giant Magellan Telescope (GMT) is one of the largest next-generation ground telescopes whose diameter is 25.4m. It has been developed since 2003, and is expected to be finished by 2018. Korea officially joined the GMT project in 2009, and actively participates in the development.

The GMT adaptive optics system
SPIE Proceedings, 2010The design of the adaptive optics (AO) system for the GMT is currently being developed. The baseline system is planned around a segmented adaptive secondary mirror (ASM), with elements similar in size to current ASM's for 8 m telescopes. A facility wavefront sensing system is planned to provide AO correction at several science instrument ports.
