Multispectral imaging captures image data in specific wavelength regions of the electromagnetic spectrum. Wavelengths may be separated by filters or acquired using instruments sensitive to specific wavelengths.

In spectral imaging (multispectral and hyperspectral), also wavelength …

Seismic tomography or imaging is a technique for imaging the Earth's subsurface with seismic waves generated by earthquakes or explosions. Velocity anomalies of seismic wave propagation in the Earth's interior are measured. The data are …
