Project Title

Design and Implementation of an Automated Imaging and Auto-Focusing System for a Remote CLaDS Methane Sensor

My project this summer dealt with the design of a robust auto-focusing imaging system for a methane sensor to be deployed in the fall of 2015. The dynamics of methane, an extremely potent greenhouse gas, are not well understood, but deciphering them is necessarily in order to properly regulate emissions. In the Princeton University Laser Sensing Lab, we built an improved sensor, which is based on a technology known as Chirped Laser Dispersion Spectroscopy (CLaDS) and is perfect for long-term sensing in traditionally difficult-to-map areas. This summer, I was responsible for the design and implementation of both hardware and software for the imaging system, which helps the sensor locate and focus on targets. My project allowed me to gain skills and knowledge in image processing, as well as an increased familiarity with optical systems. Prior to my research this summer, I was primarily interested in optics, but my positive experience has convinced me to continue to learn about computer vision and imaging. I hope to continue this research project for my senior thesis.
