The practical application of imaging spectrometers is they are used to observe the planet Earth from orbiting satellites. The spectrometer functions by recording all points of color on a picture, thus, the spectrometer is focused on specific parts of the Earth’s surface to record data. The advantages of spectral content data include vegetation identification, physical condition analysis, mineral identification for the purpose of potential mining, and the assessment of polluted waters in oceans, coastal zones and inland waterways.
Prism spectrometers are ideal for Earth observation because they measure wide spectral ranges competently. Spectrometers can be set to cover a range from 400nm to 2,500 nm, which interests scientists who are able to observe Earth by means of aircraft and satellite. The spectral resolution of the prism spectrometer is not desirable for most scientific applications; thus, its purpose is specific to recording spectral content of areas with greater spatial variations
One of these baby's could find this plane in the flip of a switch. I've searched all over the web and nothing has mentioned that were using these.
"the U.S. has the best such imagery, many of its military satellites wouldn’t be tasked for such searches."
“Many countries (including China) have a number of sensitive national security capabilities that are probably not contributing to this search,”
“If they found something, they might have to reveal the capability."
