Robotic laser sensor detects atmospheric pollution

Monday, Apr 30, 2012

Princeton University engineer Amir Khan, a postdoctoral research associate in Civil and Environmental Engineering, and colleagues, working with space scientists at the University of Texas at Dallas, will discuss how their teams combined a compact, low-power, open-path (exposed directly to the environment) laser sensor with a robotic helicopter to measure the three most important greenhouse gases – carbon dioxide, methane and water vapor – in the atmosphere at the Conference on Lasers and Electro-Optics (CLEO: 2012 (http://www,, to be held May 6-11, in San Jose, Calif.
