The range of applications in which remote detection of chemical compounds is used extends from monitoring of technological processes through diagnostics of industrial installation and environmental control up to military applications. The methods and the devices used for the passive detection of selected gases are presented. The change in the signal reaching the camera caused by the presence of gas was calculated. The successful detection can be achieved if the absorption (or emission) of a gas cloud, located between object (background) and the camera, causes signal change greater or equal to noise equivalent temperature difference (NETD) of the camera.
The theoretical section uses the method of critical analysis of CSR literature, whereas the statistical analysis of data from the authors' electronic mail survey and Responsible Business Forum (RBF) secondary research is applied to the empirical part.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
