“…This is the first step of "Come-On" project [140]. Subsequently, from December 1992 to April 1993, high-resolution imaging of astronomical targets in the infrared band was achieved with 52 units DM and 32 subapertures Hartmann sensor on the 3.6m NTT [141]. Following those early successes, observatories in various countries started AO research one after another.…”

Since the concept of adaptive optics(AO) was proposed in 1953, AO has become an indispensable technology for large aperture ground-based optical telescopes aimed at high resolution observations. This paper provides a comprehensive review of AO progress for large aperture astronomical optical telescopes including both night-time and day-time solar optical telescopes. The recent AO technological advances, such as Laser Guide Star, Deformable Secondary Mirror, Extreme AO, and Multi-Conjugate AO are focused.

“…23 However, the first published application of AO to astronomy was the ESOsupported system called COME-ON, which was successfully tested in 1989 at Observatoire de Haute Provence in France; 24,25 it was later upgraded and moved to the 3.6-m ESO observatory at La Silla, Chile. 26 In the 1980s early United States development of AO for astronomy continued at NOAO and the University of Hawaii. An innovative approach to wavefront sensing and control, the curvature sensor and bimorph mirror, was developed during this time.…”

Over its more than 30-year history, the Advanced Technologies and Instrumentation (ATI) program has provided grants to support technology development and instrumentation for ground-based astronomy. Through a combination of automated literature assessment and indepth literature review, we present a survey of ATI-funded research and its impact on astronomy and society. Award acknowledgment and literature citation statistics for ATI are comparable to a comparison astronomy grant program that does not support technology development. Citation statistics for both NSF-funded programs exceed those of the general astronomical literature. Numerous examples demonstrate the significant, long-term impact of ATI-supported research in astronomy. As part of this impact, ATI grants have provided many early career researchers the opportunity to gain critical professional experience. However, technology development unfolds over a time period that is longer than an individual grant. A longitudinal perspective shows that investments in technology and instrumentation have led to extraordinary scientific progress. © The Authors.

“…Space based instruments will be the ultimate incarnation for astronomical interferometry because of the distortions imposed by the Earth's atmosphere, however, ground based interferometers exploiting advanced adaptive optics (AO) systems [5,6] have significantly improved terrestrial systems to the point that useful science is now possible even with large apertures.…”

Understanding exoplanet formation and finding potentially habitable exoplanets is vital to an enhanced understanding of the universe. The use of nulling interferometry to strongly attenuate the central star's light provides the opportunity to see objects closer to the star than ever before. Given that exoplanets are usually warm, the 4 µm Mid-Infrared region is advantageous for such observations. The key performance parameters for a nulling interferometer are the extinction ratio it can attain and how well that is maintained across the operational bandwidth. Both parameters depend on the design and fabrication accuracy of the subcomponents and their wavelength dependence. Via detailed simulation it is shown in this paper that a planar chalcogenide photonic chip, consisting of three highly fabrication tolerant multimode interference couplers, can exceed an extinction ratio of 60 dB in double nulling operation and up to 40 dB for a single nulling operation across a wavelength window of 3.9 to 4.2 µm. This provides a beam combiner with sufficient performance, in theory, to image exoplanets.
