NettetWe have developed an integrating cavity absorption meter that is, in principal, rigorously independent of scattering effects. We review the theoretical basis for the instrument, describe one of the prototypes that has been constructed and tested, and present experimental results for absorption spectra of various samples. Measurement … Nettet27. jan. 2011 · Optical resonators (optical cavities) that are suitable for the CEAS are characterized by a high quality factor (Q-factor) >10 4 ensuring several tens of back-and-forth reflections of light during its decay and effective absorption lengths of tens of kilometres for meter-sized cavities.

Development of a point source integrating cavity absorption meter
Nettet4. apr. 2024 · [1-6] Upon photon absorption, hot electrons can store quantum mechanical information of the incident light, thus quantifying the hot electron current and energy in external circuits. [ 7 , 8 ] In combination with plasmonic nanostructures, hot electron photodetection in 2D transition metal dichalcogenides (TMD), which are promising … Nettet11. apr. 2024 · In this study, a method for double-beam quantum cascade laser absorption spectroscopy (DB-QCLAS) was developed. Two mid-infrared distributed feedback quantum cascade laser beams were coupled in an optical cavity for the monitoring of NO and NO2 (NO at 5.26 μm; NO2 at 6.13 μm). Appropriate lines in the … NettetThe heat transfer characteristics of the working fluid passing through the absorber of a solar parabolic trough collector (SPTC) can be enhanced by the creation of a turbulence effect. Therefore, a novel idea was implemented by introducing a corrugated tube (CT) absorber instead of a plain tube absorber in a solar parabolic trough collector. The … robert burns ann park
