Simultaneously realizing thermal and electromagnetic cloaking by multi-physical null medium
Yichao Liu, Xiaomin Ma, Kun Chao +6
Simultaneously manipulating multiple physical fields plays an important role in the increasingly complex integrated systems, aerospace equipment, biochemical productions, etc. For…
A Near-Infrared Pyramid Wavefront Sensor for the MMT
Jacob Taylor, Suresh Sivanandam, Narsireddy Anugu +8
The MMTO Adaptive optics exoPlanet characterization System (MAPS) is an ongoing upgrade to the 6.5-meter MMT Observatory on Mount Hopkins in Arizona. MAPS includes an upgraded adap…
Active thermal metasurfaces for remote heating/cooling by mimicking negative thermal conductivity
Yichao Liu, Kun Chao, Fei Sun +3
Remote temperature control can be obtained by a long-focus thermal lens that can focus heat fluxes into a spot far away from the back surface of the lens and create a virtual therm…
Optical Design and Wavelength Calibration of a DMD-based Multi-Object Spectrograph
Shaojie Chen, Matthew C. H. Leung, Xuefeng Yao +3
The multi-object spectrograph (MOS) has been the benchmark for the current generation of astronomical spectrographs, valued for its ability to acquire the spectra of hundreds of ob…
Accurately Measuring Hyperspectral Imaging Distortion in Grating Spectrographs Using a Clustering Algorithm
Matthew C. H. Leung, Shaojie Chen, Colby Jurgenson
Grating-based spectrographs suffer from smile and keystone distortion, which are problematic for hyperspectral data applications. Due to this, spectral lines will appear curved and…
Design and development of a high-speed Visible Pyramid Wavefront Sensor for the MMT AO system
Narsireddy Anugu, Olivier Durney, Katie M. Morzinski +16
MAPS, MMT Adaptive optics exoPlanet characterization System, is the upgrade of legacy 6.5m MMT adaptive optics system. It is an NSF MSIP-funded project that includes (i) refurbishi…
Gemini Infrared Multi-Object Spectrograph: Instrument Overview
Suresh Sivanandam, Scott Chapman, Luc Simard +27
The Gemini Infrared Multi-Object Spectrograph (GIRMOS) is a powerful new instrument being built to facility-class standards for the Gemini telescope. It takes advantage of the late…
The Rapid Transient Surveyor
Christoph Baranec, Jessica R. Lu, Shelley A. Wright +8
The Rapid Transient Surveyor (RTS) is a proposed rapid-response, high-cadence adaptive optics (AO) facility for the UH 2.2-m telescope on Maunakea. RTS will uniquely address the ne…
The InfraRed Imaging Spectrograph (IRIS) for TMT: Reflective ruled diffraction grating performance testing and discussion
Elliot Meyer, Shaojie Chen, Shelley A. Wright +6
We present the efficiency of near-infrared reflective ruled diffraction gratings designed for the InfraRed Imaging Spectrograph (IRIS). IRIS is a first light, integral field spectr…
The Infrared Imaging Spectrograph (IRIS) for TMT: Volume phase holographic grating performance testing and discussion
Shaojie Chen, Elliot Meyer, Shelley A. Wright +5
Maximizing the grating efficiency is a key goal for the first light instrument IRIS (Infrared Imaging Spectrograph) currently being designed to sample the diffraction limit of the…
The Infrared Imaging Spectrograph (IRIS) for TMT: Instrument Overview
Anna M. Moore, James E. Larkin, Shelley A. Wright +31
We present an overview of the design of IRIS, an infrared (0.84 - 2.4 micron) integral field spectrograph and imaging camera for the Thirty Meter Telescope (TMT). With extremely lo…
