Quasi-simultaneous measurement of line and background absorption

Alternative measurements of the absorption of the hollow cathode lamp radiation and of the radiation of the continuum source can also be taken in a rapidly alternating mode, and accordingly a quasi-simultaneous measurement of line and background absorption, as required with transient signals, becomes possible. This can be realized by a rotating mirror and is sufficiently rapid to enable a high time resolution, as shown by Berndt et al. [305].
