IMPROVING SPECTROSCOPIC TECHNIQUES BY A SCANNING MULTICHANNEL METHOD

In this work we show that some disadvantages (e.g., limited range of the recorded spectra, different noise and sensitivity of each detection element, and fixed spectral distance of the detection elements) can be excluded by using what we call the scanning multichannel technique (SMT). A calculation of the measurement time for characteristic single-channel and multichannel detectors results in the fact that SMT is, like MT, an order of magnitude faster than the single-channel technique (SCT). In some particular cases SMT results in measurements times shorter than those for MT. We conclude that SMT combines the advantages of MT and SCT.
