Abstract: Carbon dioxide (CO2) is the most important greenhouse gas in the atmosphere, playing a crucial role in the greenhouse effect and climate change. Lidar, with its high spatiotemporal ...
Optical photothermal infrared (O-PTIR) spectroscopy is an infrared super-resolution measurement technique where a shorter ...
Abstract: In this letter, we proposed a method for multipoint gas sensing by using intrapulse absorption spectroscopy and cascaded, branching gas cells. For methane sensing, a distributed feedback ...
