Spectral line intensity
The analysis of line intensity ratios is an important tool to obtain information about laboratory and space plasmas. In emission spectroscopy, the intensity of spectral lines can provide various information about the plasma (or gas) condition. It might be used to determine the temperature or density of the plasma. Since the measurement of an absolute intensity in an experiment can be challenging, the ratio of different spectral line intensities can be used to achieve information abo… WebJan 1, 2016 · Since many computer vision algorithms assume a linear relationship between sensor irradiance and the measured image intensity, it is important to identify saturated …
