An overview of the 3 facility instruments and 2 strategic interferometric instruments under construction for the Large Binocular Telescope is presented. Planned optical instrumentation includes the Large Binocular Camera (LBC), a pair of wide-field (25′ × 25′) UB/VRI optimized mosaic CCD imagers at the prime focus, and the MultiObject Double Spectrograph (MODS), a pair of dual-beam blue-red opt...

This article presents a miniaturized electron spin resonance (ESR) probe for deducing the position of a surgical instrument on an MR image. The ESR probe constructed was small enough to fit inside a 14-G biopsy needle sheath, and position information of the sheath could be acquired using a simple gradient sequence. The position accuracy was estimated from needle trajectories as inferred from th...

A gas sensor based on correlation spectroscopy using a FPI with long cavity length (>500 μm) as a modulator is presented. Eventually the FPI and the optical detector will be integrated within a MEMS structure. ©2005 Optical Society of America OCIS codes: (220.4830) Optical systems design; (120.4640) Optical instruments; (120.4570) Optical design of instruments

Introduction The absorption of near infrared light by materials provides information about the chemistry and structure of those materials by probing their molecular vibrations. The infrared spectra of biological macromolecules have distinct absorbances that allow Fourier Transform InfraRed (FTIR) spectroscopy to monitor macromolecular changes. FTIR can be carried out in aqueous solution, organi...

In this Chapter† we review the challenges of, and opportunities for, 3D spectroscopy, and how these have lead to new and different approaches to sampling astronomical information. We describe and categorize existing instruments on 4m and 10m telescopes. Our primary focus is on grating-dispersed spectrographs. We discuss how to optimize dispersive elements, such as VPH gratings, to achieve adequ...
