Title (EN) COMPACT OPTICAL GAS DETECTION SYSTEM AND APPARATUS
(FR) SYSTÈME ET APPAREIL DE DÉTECTION DE GAZ OPTIQUE COMPACT
Abstract:
(EN) System and apparatus for portable gas detection. Specifically, this disclosure describes apparatuses and systems for optical gas detection in a compact package. There is a need for a very compact, low-power, gas detection system for gases such as CO2, NOx, water vapor, methane etc. This disclosure provides an ultra-compact and highly efficient optical measurement system based on principals of optical absorption spectroscopy. It reduces the size of the instrument as well its power consumption by more than an order of magnitude making it possible to deploy it widely. There is an identified need for large number of distributed gas sensors to improve human health, environment, and save energy usage.
(FR) La présente invention concerne un système et un appareil de détection de gaz portable. Spécifiquement, la présente invention concerne des appareils et des systèmes de détection de gaz optique dans un boîtier compact. Il existe un besoin d'un système de détection de gaz très compact, à faible puissance pour des gaz tels que CO2, NOx, la vapeur d'eau, le méthane, etc. L'invention concerne un système de mesure optique ultracompact et très efficace basé sur des principes de spectroscopie d'absorption optique. Il réduit la taille de l'instrument ainsi que sa consommation d'énergie de plus d'un ordre de grandeur, ce qui permet de le déployer largement. Il existe un besoin identifié d'un grand nombre de capteurs de gaz distribués pour améliorer la santé humaine, l'environnement et économiser l'utilisation d'énergie.
