摘要： In einem neuartigen faseroptischen Differentialrefraktometer (FODR) für die Messung des Brechzahlinkrements Dn oder der Konzentrationsdifferenz DC wird Licht aus einer Lichtquelle 1 in das Tor I eines faseroptischen Richtkopplers 2 eingekoppelt und dann durch den Richtkoppler 2 in ein Tor II geleitet. Am Ende von Tor II wird das Licht durch eine Linse 3 kollimiert. Das kollimierte Licht wird weiter durch eine geteilte Refraktometerküvette 4 geleitet und durch einen Spiegel 5 zurückreflektiert. Das reflektierte Licht wird nochmals durch die geteilte Refraktometerküvette 4 geleitet. Bei jedem Durchlauf durch die Refraktometerküvette 4 wird das Licht gebrochen, wenn die Lösungen in den zwei Abteilungen der geteilten Refraktometerküvette 4 unterschiedliche Brechzahlen haben. Deshalb kann nur ein Bruchteil des reflektierten Lichtes von der Linse 3 in das Tor II fokussiert werden, der seinerseits eine Funktion des Ausmaßes der Brechung ist. Das von Tor II aufgenommene Licht wird vom Richtkoppler 2 zum Photodetektor 6 weitergeleitet.
摘要翻译：在用于测量折射率增量Dn或浓度差DC的新型光纤差示折射计（FODR）中，来自光源1的光耦合到光纤定向耦合器2的栅极I中，然后定向通过定向耦合器2进入门II。光在门II的端部由透镜3准直。准直光被进一步引导通过分开的折射计4，并被反射镜5反射回来。反射光再一次通过分开的折射计4被引导。如果每个通过折射计4，则光被折射裂开折射计4的两个隔室具有不同的折射率。因此，只有一部分反射光可以被透镜3聚焦到栅极II中，并且这个部分又是折射程度的函数。由栅极II接收的光被定向耦合器2进一步引导到光电检测器6

摘要： A flow cell for differential refractive index detection. The flow cell includes a transparent body that extends from a first end to a second end along a longitudinal axis. The transparent body defines a sample prism chamber and reference prism chamber. The sample prism chamber is configured to allow fluid flow between the first and second ends of the transparent body along the longitudinal axis. The reference prism chamber is configured to receive a reference fluid. The sample and reference prism chambers each include a grating comprising a plurality of grooves extending along the longitudinal axis in the direction of fluid flow.

摘要： Reference materials of differing indices of refraction are incorporated into liquid compositions to monitor the solidification process of these liquid compositions. Light waves are used to indirectly measure the difference between the index of refraction of the solidifying composition and the reference material. The method provides an accurate in situ indication of the completion of the solidification process as well as a monitor of the degree of solidification during the solidification process.
