Detecting device for a medium inside a tube portion
First Claim
1. A detecting device for a medium inside a tube portion, the detecting device comprising:
- at least one light source arranged at a first position relative to the tube portion adapted to be transilluminated with light and configured to irradiate light onto the tube portion in a light path;
a detector unit arranged at a second position relative to the tube portion and configured to receive light from the at least one light source passed through the tube portion and to analyze a medium inside the tube portion in a spatially resolving manner;
a homogenizing device arranged between the at least one light source and the tube portion and configured, for detecting and quantifying differences in brightness due to local differences of the medium inside the tube portion, to create at least one of a homogenous or isotropic distribution of the light from the at least one light source before the light enters the tube portion, the homogenizing device including a light absorbing substance introduced to the homogenizing device at predetermined concentrations to provide a variably light-absorbing function of the homogenizing device, the light absorbing substance introduced to the homogenizing device along a direction perpendicular to a transilluminating direction in predetermined areas of the homogenizing device; and
first and second walls between which at least one of the at least one light source or the homogenizing device is arranged, wherein the first and second walls extend in a longitudinal direction bordering the light path and without interrupting the light path.

Abstract
A detecting device for a medium inside a tube portion comprises at least one light source being arranged at a first position relative to the tube portion adapted to be transilluminated with light and being configured to irradiate light onto the tube portion, a detector unit being arranged at a second position relative to the tube portion and being configured to receive light from the at least one light source passed through the tube portion and to analyze a medium inside the tube portion in a spatially resolving manner, and a homogenizing device being arranged at a position between the at least one light source and the tube portion and being configured, for detecting and quantifying differences in brightness due to local differences of the medium inside the tube portion, to create a homogenous and/or isotropic distribution of the light from the at least one light source before the light enters into the tube portion.
