This paper probes into data information extraction and classification methods for imaging spectrometer, puts a scheme to process and classify the information of imaging spectrometer.
His main tool is a device called a secondary-ion mass spectrometer.
The spectrometer will look again for sodium when it flies through the plumes on October 9, says Hunter Waite of the Southwest Research Institute in San Antonio.
They grow their bacteria on a stainless steel plate, and use a laser to vaporise their signalling molecules, feeding these into a mass spectrometer to catalogue the molecules present.
To measure this, archaeologists use a device called an accelerator mass-spectrometer.
It will gather data from 56,000 points around the globe with two detectors. One is a spectrometer that measures sunlight reflected from the Earth's surface.
"At this point, the origin of Mercury's large core is still a mystery," said Larry Nittler, a cosmochemist at the Carnegie Institution of Washington who led the X-ray spectrometer study.
One is a spectrometer that measures sunlight reflected from the Earth's surface.
The instruments on the Global Hawk rival those found in NASA's tropical weather satellites. The sounding radiometer can also work as a spectrometer.
The flat structure of spectrometer can enlarge usage scope.
"mass spectroscopy A mass spectrometer uses electrical means to detect the sorted ions, while a mass spectrograph uses photographic or other nonelectrical means; either device is a mass spectroscope."
High-speed rotary Fourier transform spectrometer has nonlinearity of optical path differences (OPD) because of refractor's rotating.
Regulating spectrometer has a important action in training university students'basic skill of experiment.
The fibres were replaced at regular intervals over the course of seven days and taken away for analysis by a device called a gas chromatograph-mass spectrometer.
Anomalies are resolved by the sweep spectrometer.
