WebFull width at half maximum (FWHM) is used when determining the spectral resolution. Here you can learn more. Full width at half maximum (FWHM) is the width of the spectrum … WebFWHM is Full Width Half Maximum. Take the maximum of your transmission peak, identify the points either side of the peak where the transmission is half the maximum, and the full width is the distance along the wavelength axis between those two points. It's just a way of measuring the width of a peak.
WebThe linewidth of a cavity is commonly defined as the Full Width at Half Maximum (FWHM) of the resonance peak, which we use here. But other definitions are also used, for example the Half Width at Half Maximum (HWHM) and the pole frequency fp f p, which both are equal to half the FWHM. The linewidth tells us how large the frequency band is that ... WebMar 13, 2024 · It took a bit to figure out how best to calculate the ‘fwhm’ vector in the absence of findpeaks.
