Description

This module is one of three pertaining to the role of optics and lasers in spectroscopy.

When you have finished this module you will be able to:
• Define remote sensing and spectroscopy and tell how they are related.
• Describe three instruments used to analyze spectra.
• Describe an instrument used to determine atomic mass.
• Identify three general types of spectroscopy.
• Identify the five wavelength regions of common use in remote sensing.
• Calculate the dispersion and chromatic resolving power for a prism.
• Draw a diagram of a grating spectrometer.
• Calculate the linear dispersion for a prism spectrometer.
• Draw a schematic diagram for a spectrophotometer.
• Describe the six main parts of a complete remote sensing process.
• Describe what is meant by atmospheric windows and how sensors are chosen to match them.
• Describe how remote sensing from foliage, water, and heated buildings, for example, is carried out.
• Distinguish between active and passive sensors.
• Identify four platforms generally used in remote sensing.
• Calculate the resolution cell for a sensor given its altitude and instantaneous field of view (IFOV).
• Distinguish between weather satellites and Earth-surface satellites.
• Describe characteristics of a GOES weather satellite.
• Describe characteristics of a LANDSAT satellite.
• Describe how a spectrophotometer is used to determine absorption/transmission through a substance.
• Use the Beer-Lambert law to relate transmission and absorption for a medium.
