Gas Analysis with Laser-Based Sensors

Caption: Scientists can analyze atmospheric gas concentrations with laser-based sensors that use systems similar to the one illustrated above. The sensor instrument directs a laser through gas and, based on how much laser light is absorbed by a sample, scientists can determine the specific gases present and their concentrations.
