The main problem in the application of radiation pyrometry to the measurement of true surface temperatures is the large error arising from the unknown or varying emissivity of the surface. The nature of the additional information required for the class of techniques which utilize only the thermal radiation emitted from the surface is discussed.

A multi-wavelength opacimeter for NOX and soot
2015 9th International Conference on Sensing Technology (ICST), 2015A novel method to simultaneously determine the concentration of particles and NO2, the main pollutants in the exhaust of diesel engines, is presented. It is based on multi-wavelength extinction measurement followed by a mathematical inversion algorithm. This paper gives an overview of the extinction measurement in general and extends the principle to a

Hybrid multi-wavelength photoacoustic imaging
2018 40th Annual International Conference of the IEEE Engineering in Medicine and Biology Society (EMBC), 2018Multi-wavelength photoacoustic (PA) imaging has been studied extensively to explore the spectroscopic absorption contrast of biological tissues. To generate strong PA signals, a high-power wavelength-tunable pulsed laser source has to be employed, which is bulky and quite expensive.

Multi-Wavelength Luminosity Functions of Galaxies
AIP Conference Proceedings, 2003Multivariate or multi‐wavelength luminosity functions will reveal the interplay between star formation, chemical evolution, and absorption and re‐emission of dust within evolving galaxy populations. By using principal component analysis to reduce the dimensionality of the problem, I optimally extract the relevant photometric information from large ...
