Abstract:
The apparatus comprises a receiving body (1) for receiving the reaction containers (3) carrying the samples to be analyzed, with means (4,4',4'',5,5',5'',6,6') for causing each of the reaction containers to be passed through by a luminous signal of controlled wavelength, having means for conducting it to a scanning head where the luminous signals are picked up by a single CCD sensor (12), constituting a digital processing system for evaluating the absorbency of the corresponding sample.
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:
An optical fiber splitter device comprising at least two optical fibers of different lengths is disclosed for partial or complete compensation of the optical path difference between waves interfering to generate a hologram or an interferogram. Various implementations of this fiber splitter device are described in apparatuses for holographic and interferometric imaging of microscopic and larger samples.

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.
