Sentences with phrase «tunable filters»

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.

Filters isolate a specific communication channel from all the others and tunable filters give a network controller the freedom to select the frequency and bandwidth for each channel and change them on the fly.

«To do this,» explains Antonio Cabrera Lavers, head of astronomy at the GTC and one of the authors of the paper, «we have used for the first time the blue tunable filter of OSIRIS to take a deep image centred on the emission from the recombination lines of one of the oxygen ions in the planetary nebula 6778.»

In blue, the emission associated with weak lines of ion O + + recombination, taken with the OSIRIS tunable filter blue instrument in the GTC.

The combination of a large telescope such as the GTC and an instrument with a tunable filter, such as OSIRIS has proved to be an ideal combination.

The tunable filter that Shi and his colleagues designed and tested has a tuning span of 670 GHz, much greater than the approximately 100 GHz span other silicon - based filters have achieved.

Shi and his colleagues have designed a tunable filter — an important component of high - capacity optical networks — that should save both money and energy because it can be readily integrated onto a photonic chip.

Going forward, the researchers plan to integrate the tunable filter with other components on the same chip to test chip - scale flexible optical networking.

The two new devices — a modulator and a tunable filter — are as energy - efficient as some of the best devices around, the researchers say, and were built using a standard IBM advanced Complementary Metal - Oxide Semiconductor (CMOS) process — the same chip - making process used to build many commercially available chips, some of which are found in Sony's Playstation 3 and also in Watson, the supercomputer that won Jeopardy! in 2011.

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.

Not exact matches

Contributions to this have been made in images obtained by the Instituto de Astrofísica de Canarias and taken thanks to the tunable blue filter of the OSIRIS instrument on the Gran Telescopio CANARIAS (GTC) at the Roque de los Muchachos Observatory (Garafía, La Palma).

This means that self - assembled structures could for instance be used to create filters with tunable porosity.

The bandwidth - tunable silicon filter uses periodic nanostructures to filter a single channel from all input frequencies.

The samples were excited with a NdYAG - pumped wavelength - tunable dye laser (Sirah Laser, Kaarst, Germany) and imaged with a f# 1.2 50 mm lens (Nikkor, Japan) and a low - noise cooled 512 × 512 16 - bit CCD camera (VersArray, Princeton Instruments, Acton MA), using 10 nm FWHM band - pass interference filters (Chroma, Bellows Falls, VT) centered at 610, 670 and 710 nm.
