Abstract

Abstract Translated from German Die vorliegende Erfindung betrifft einen Remissionsmeßkopf, der so ausgebildet ist, daß Verfälschungen der Meßergebnisse durch Glanzreflexe vermieden werden, ohne daß die Verwendung herkömmlicher Glanzfallen oder Blenden erforderlich ist. Verfälschungen der Meßergebnisse durch Glanzreflexe, durch Struktureinflüsse und durch Inhomogenitäten auf der zu messenden Fläche werden weiter dadurch vermieden, daß mehrere Sender von einem Empfänger oder mehrere Empfänger von einem Sender in jeweils gleichem Abstand angeordnet sind. Besonders vorteilhaft sind mehrere Sender und mehrere Empfänger die abwechselnd zueinander matrixförmig angeordnet sind. The present invention relates to a reflectance measuring head which is designed in such a way that falsification of the measurement results by gloss reflections is avoided without the use of conventional gloss traps or diaphragms being necessary. Falsifications of the measurement results due to gloss reflections, structural influences and inhomogeneities on the surface to be measured are further avoided by arranging several transmitters from one receiver or multiple receivers from one transmitter at the same distance from one another. A plurality of transmitters and a plurality of receivers which are arranged alternately in a matrix form are particularly advantageous.
