Zusammenfassung:An interferometric arrangement for detecting a substance having structured absorption spectrum by means of a radiation source (L) with the substance to be examined (K), an interference filter whose thickness determines the spacing of the interference lines and a detector (D) in its beam path. The interference filter is an electrically tunable filter (E) containing a plate of electrooptical material (P) and partially absorbent, metallised end faces (S). ……
