Abstract: A method and a device for generating and for detecting a Raman spectrum enables an automated, or automatable, and at the same time quantitative SERD spectroscopy (for example concentration measurement series). To this end, during the SERD spectroscopy, a first spectrum and a second spectrum are standardized in relation to one another in terms of intensity values and a first difference spectrum is subsequently calculated, a second difference spectrum is calculated, the first difference spectrum is converted into a first transformation spectrum, the second difference spectrum is converted into a second transformation spectrum, and the Raman spectrum is calculated by adding the first transformation spectrum and the second transformation spectrum.

Abstract: A remote sensing method for detecting and analyzing gases, vapors and flame plumes using an imaging spectrometer. The spectrometric instrument uses Image Multispectral Sensing (IMSS) technology, enhanced by advanced imaging processing techniques and micro-miniature circuitry. These enhancements provide a portable instrument with the capability to remotely detect and image gases, including gas leaks. The technology also provides an analysis of the gas including chemical species and concentrations. The instrument can also remotely detect, image and analyze flames and plumes in the same manner, providing an analysis of the chemical species and concentrations in the flame. Advanced image processing techniques are used to provide gas and plume images and analysis to the operator. These processing algorithms are implemented in micro-miniature circuits such as digital signal processors (DSP's) and field programmable gate arrays (FPGA's) to provide a field portable instrument.
