WitrynaDr. Robert Green is a science co-investigator on the CRISM imaging spectrometer for Mars, Instrument Scientist for the M3 imaging spectrometer on Chandrayaan-1, … In imaging spectroscopy (also hyperspectral imaging or spectral imaging) each pixel of an image acquires many bands of light intensity data from the spectrum, instead of just the three bands of the RGB color model. More precisely, it is the simultaneous acquisition of spatially coregistered images in many spectrally contiguous bands.
WitrynaThe term spectrophotometer can refer to quite a variety of instruments that measure light, with the exact definition depending on the area of science or industry. In all cases the term ‘photo’ is used to indicate that the spectrometer is for the quantitative measurement of light intensity with wavelength. WitrynaSpectrometer is a broad term often used to describe instruments that measure a continuous variable of a phenomenon where the spectral components are somehow mixed. In visible light a spectrometer can separate white light and measure individual narrow bands of color, called a spectrum. A mass spectrometer measures the …
