The use of liquid crystal adaptive optics devices in astronomy [PDF]
, 1991 Images obtained from large astronomical telescopes are distorted and blurred by the effects of the atmosphere. In order to compensate for this, an adaptive optics system can be incorporated downstream from the telescope focus.

Review: Nutritive evaluation of forages by near infrared reflectance spectroscopy
, 2005 11 pages.Since the potential of near infrared (NIR) spectroscopy for forage evaluation was discovered three decades ago, it has become clear that it is a powerful tool for the estimation of chemical components in these feed-stuffs.

Journal of Low Temperature PhysicsWe report on simulations of a novel design of optical titanium nitride (TiN)- based Kinetic Inductance Detectors (KIDs) in order to improve their response to optical photons. We propose to separate the meander from the substrate to trap hot phonons generated by optical photons, preventing their rapid propagation through the substrate.

, 2019 Gaia is a revolutionary space mission developed by ESA and is delivering 5 parameter astrometry, photometry and radial velocities over the whole sky with astrometric accuracies down to a few tens of micro-arcseconds. A weakness of Gaia is that it only operates at optical wavelengths.

Silicon photonic modulators for the mid-infrared
, 2013 Mid-infrared group-IV material photonics is an emerging field, which aims to migrate techniques used for near-infrared silicon photonics to longer wavelengths, and to address applications in areas such as environmental and bio-chemical sensing, homeland ...

Cerebral near-infrared spectroscopy guided neonatal intensive care management for the preterm infant [PDF]
Infants requiring admission to the neonatal intensive care unit (NICU) are particularly vulnerable to developing brain injury. The severity of the underlying clinical conditions and the complexity of care call for continuous, cot-side, non-invasive ...
