WebMar 15, 2024 · The main disadvantage of the electromagnetic acoustic transducer (EMAT) is low energy-conversion efficiency and low signal-to-noise ratio (SNR). This problem can be improved by pulse compression technology in the time domain. In this paper, a new coil structure with unequal spacing was proposed for a Rayleigh wave EMAT (RW-EMAT) to … WebApr 8, 2024 · Raman spectrometers should have a good light source. Usually, they use continuous lasers characterized by high stability and a narrow bandwidth. Another important component of the Raman spectrometer is a filter that separates a wanted signal containing the Raman spectrum lines from the Rayleigh signal of the radiation source.

WebBlocking Rayleigh Scattering. In order to obtain high signal-to-noise in Raman measurements, it is necessary to block Rayleigh scattering from reaching the detector while transmitting the Raman signal. It's possible to use a double or triple grating spectrometer to accomplish rejection of the background signal. impact investment exchange iix singapore https://shafersbusservices.com
