Capture realtime images of gas leaks with this technology

By Scott Jenkins |

New gas-cloud imaging technology from Rebellion Photonics (Houston; www.rebellionphotonics.com) monitors facilities for gas leaks and is capable of imaging chemical releases in realtime, identifying and quantifying gas clouds over large sections of a facility (photo). The company’s technology aims to improve todays alarm-based, point-detector systems, which are limited in coverage area and in their ability to visualize emissions. Growing out of research at Rice University (Houston; www.rice.edu), Rebellion’s Gas-Cloud Imaging camera captures infrared (IR) spectral information about a range of gaseous chemicals from digital video images instantly. The process is known as “snapshot” hyperspectral imaging (HSI). The company has also developed optical hardware to allow the “snapshot” HSI, as well as algorithms that can process the images at video rates, instead of over a much longer period, as had been the case with previous efforts with HSI. For carrying out HSI, Rebellion has developed the fully automatic Gas-Cloud Imaging camera, which is capable of detecting long-wavelength (7.5–14.5 micron) IR spectra from a variety of gases across a mosaic of fields of view at a chemical facility. The camera…
