Testing and alignment of the LBTI
Proceedings of SPIE, 2010The Large Binocular Telescope Interferometer (LBTI) has been developed and tested and is almost ready to be installed to LBT mount. In preparation for installation, testing of the beam combination and phasing of the system have been developed. The testing is currently in progress.

Design considerations for LBTI observer interface
Proceedings of SPIE, 2010We outline the design considerations and principles for developing a graphical user interface for configuring and operating Large Binocular Telescope Interferometer (LBTI) on sky, and examine the "weblication" methodology to deliver this astronomical software over the web.

Improved Constraints on the Disk around MWC 349A from the 23 m LBTI [PDF]
Astrophysical Journal, 2017 Abstract We present new spatially resolved observations of MWC 349A from the Large Binocular Telescope Interferometer (LBTI), a 23 m baseline interferometer made up of two, co-mounted 8 m telescopes. MWC 349A is a B[e] star with an unknown evolutionary state.

Commissioning the LBTI for use as a nulling interferometer and coherent imager
Proceedings of SPIE, 2014The Large Binocular Telescope Interferometer (LBTI) is a strategically important instrument for exploiting the use of the LBT as a 22.7 m telescope. The LBTI has two science cameras (covering the 1.5-5 μm and 8-13 μm atmospheric windows), and a number of observing modes that allow it to carry out a wide range of high-spatial resolution observations ...

The LBTI Fizeau imager – II. Sensitivity of the PSF and the MTF to adaptive optics errors and to piston errors [PDF]
Monthly Notices of the Royal Astronomical Society, 2017 We show numerical simulations with monochromatic light in the visible for the LBTI Fizeau imager, including opto-dynamical aberrations due here to adaptive optics (AO) errors and to differential piston fluctuations, while other errors have been neglected.

L'-band AGPM vector vortex coronagraph's first light on LBTI/LMIRCam [PDF]
Proceedings of SPIE, 2014 We present the first observations obtained with the L'-band AGPM vortex coronagraph recently installed on LBTI/LMIRCam. The AGPM (Annular Groove Phase Mask) is a vector vortex coronagraph made from diamond subwavelength gratings. It is designed to improve the sensitivity and dynamic range of high-resolution imaging at very small inner working angles ...

Overview and prospects of the LBTI beyond the completed HOSTS survey
Optical and Infrared Interferometry and Imaging VII, 2020The Large Binocular Telescope Interferometer (LBTI) combines the light from the two 8.4 m primary mirrors of the LBT for interferometry and adaptive optics (AO) imaging. With two high performance, state-of-the-art AO systems and adaptive secondary mirrors, a cryogenic instrument, and an edge-to-edge baseline of 23 m, the LBTI is a unique instrument ...

MegaMIR: a Fizeau thermal infrared camera for the LBTI
SPIE Proceedings, 2006The Megapixel Mid-infrared Instrument (MegaMIR) is a proposed Fizeau-mode camera for the Large Binocular Telescope operating at wavelengths between 5 and 28 μm. The camera will be used in conjunction with the Large Binocular Telescope Interferometer (LBTI), a cryogenic optical system that combines the beams from twin 8.4-m telescopes in a phase ...
