Sentences with phrase «tunable infrared»

The approach, called tunable infrared laser direct absorption spectroscopy, detects the ratio of methane isotopes, which can provide a «fingerprint» to differentiate between two common origins: microbial, in which microorganisms, typically living in wetlands or the guts of animals, produce methane as a metabolic byproduct; or thermogenic, in which organic matter, buried deep within the Earth, decays to methane at high temperatures.

«Tunable infrared OPA light sources today cost around a $ 100,000 and take up a good bit of space on a tabletop or lab bench,» said study lead author Yu Zhang, a former Rice graduate student at LANP.

In fact, the UCSB researchers are collaborating with Raytheon Vision Systems in Goleta to investigate applications of their discoveries in the development of tunable filters and switchable shutters for infrared cameras.

To make these fascinating discoveries, the JWST will rely primarily on four scientific instruments: a near - infrared (IR) camera, a near - IR multi-object spectrograph, a mid-IR instrument and a tunable filter imager.

The paper, «Photoluminescent Gold - Copper Nanoparticle Alloys with Composition - Tunable Near - Infrared Emission,» first appeared online April 3 and later in print April 10 in JACS (Journal of the American Chemical Society).

Optical generation and detection of the PNBs was performed with a previously developed photothermal laser microscope [44] equipped with a dual pulsed laser (STH - 01, Standa Ltd, Vilnius, Lithuania): each pulse 0.5 ns, the wavelength of 532 nm (matching plasmon resonances of gold spheres of 60 nm) and tunable near - infrared (matching plasmon resonances of gold nanorods and nanoshells that were employed).
