Method and Detection Device for the Imaging Detection of a Sample
First Claim
1. A method for the imaging detection of a sample in a sample vessel (10), which is longitudinally elongate and transparent at least in sections, by means of a detection arrangement comprising:
- a sample vessel holder (23, 30) for stably supporting the sample vessel (10) in a housing (21), with the sample vessel holder (23, 30) having in the region of at least one longitudinal side of the sample vessel (10) a side viewing window which at least in sections uncovers the longitudinal side, and the sample vessel holder (23, 30) also having in the region of at least one end side of the sample vessel (10) an end viewing window (34, 35) which at least in sections uncovers this end side,a first illumination arrangement comprising at least one light source (200) for illuminating the sample and/or the sample vessel (10), with the light source (200) being arranged adjacent to the end viewing window (34, 35) and the sample and/or the sample vessel being able to be illuminated through the end viewing window (34) by means of the light source (200),an imaging photodetector (22) for the imaging detection, at least in sections, of the light emitted through a side viewing window due to the illumination of the sample and/or the sample vessel (10),a digital data processing unit for image processing and controlling the photodetector (22),characterizedin that a second illumination arrangement with at least one light source is provided, by means of which the sample and/or the sample vessel (10) can be illuminated through a side viewing window, and in which the method comprises the following steps;
illuminating the sample and/or the sample vessel (10) by means of the first illumination arrangement,using the photodetector (22) to record a first image of the sample and/or sample vessel (10) illuminated by the first illumination arrangement,illuminating the sample and/or the sample vessel (10) by means of the second illumination arrangement,using the photodetector (22) to record a second image of the sample and/or sample vessel (10) illuminated by the second illumination arrangement,superposing the first and the second image by means of the digital data processing apparatus, anddisplaying the resultant superposed image on a display apparatus connected to the digital data processing apparatus.

Abstract
The invention relates to a device for detecting a sample in a longitudinal sample container (10), comprising a sample container holder (30) for holding the sample container in a housing. Said sample container holder comprises a side viewing window in the region of at least one longitudinal side of the sample container, and a front viewing window (35) in the region at least one front side of the sample container. Said device also comprises a first illumination arrangement for illuminating the sample container through the front viewing window, a second illumination arrangement for illuminating the sample container through the side viewing window, and an imaging photodetector for detecting a first image of the sample illuminated by means of the first illumination arrangement, and a second image of the sample illuminated by means of the second illumination arrangement. Said detection takes place through the side viewing window. Said device further comprises a digital data processing unit for overlaying the first and second images and for representing the resulting overlay image on a display device connected to the data processing unit.
