Fujitsu Optical Components and Furukawa Electric to Jointly Develop Integrated Receivers for 40Gbps and 100Gbps Optical Networks Aug 19, 2009
A component used for coherent signal demodulation for either heterodyne or intradyne detections. It would mix the incoming optical signal with the reference optical signal from optical source in receiver side, and then deliver the combined optical signals to balanced receivers. (JCN Network, Japan)
NRL scientist receives patent for rugged-lightweight spectrometer assembly Jul 23, 2009
This is a schematic diagram of the Spatial Heterodyne Hpectrometer (SHS) Interferometer. Naval Research Laboratory (NRL) Space Science Division scientist, Dr. Christoph R. Englert, is awarded patent by the United States Patent and Trademark Office for a more cost effective, rugged and lightweight compression assembly design for spatial heterodyne spectrometer (SHS) interferometer applications ... Field-widened spatial heterodyne spectroscopy was conceived in the late 1980s by Fred Roesler,... (EurekAlert! -- Business News)
Herschel's first images promise bright future Jul 14, 2009
Herschel's Heterodyne Instrument for the Far-Infrared (HIFI) also struck gold on its first attempt, detecting ionised carbon, carbon monoxide and water in a massive star-forming region known as DR21, in the constellation Cygnus. The instrument works by zooming in on specific wavelengths to reveal the fingerprint spectral lines unique to each atom and molecule. (Astronomy Now Online)
