    Abstract: Die Erfindung betrifft ein Fotometer (1) bei dem mittels eines Zerhackers (17,18,29,31) eine Meßphase, eine Referenzphase und eine Dunkelphase er­zeugt werden. Diese Phasen sind zeitlich versetzt, so daß für alle Phasen ein einziger Detektor (23) vorgesehen sein kann. In dem Fotometer (1) ist das zu messende Objekt (6) zwischen zwei Lichtleitern (13,14) vorge­sehen, wobei der eine Lichtleiter (14) zu dem Detektor (23) und der an­dere Lichtleiter (13) zu dem Zerhackereingang (17) führt. Der Zerhacker­ausgang (18) ist mit einem weiteren Lichtleiter (19) auf den Detektor (23) geführt (Fig. 1).

    Abstract: A device is proposed for measuring the composition of fluids, in particular of constituents of exhaust gases from internal combustion engines, in which a light ray (32, 31) is used to irradiate the exhaust gas to be measured over the length of a measuring section (29) and is weakened or changed more or less, depending on the content of constituents. The light signal being received is advantageously registered by a measured length light receiver (18) which is shielded light-tight against the light emitting light source (14) and is evaluated in relation to the original light emission, in an evaluation circuit (26). In this simple way, accurate information is obtained of the exhaust gas clouding and of the loading of a fluid or gas with constituents which are optically active.
