| 摘要 |
The invention concerns an apparatus (100, 200, 1000) for contactless measurement of infrared radiation of two regions (22, 24) of a rail car, wherein the apparatus comprises a first infrared sensor adapted to measure the first region (24), and a second infrared sensor adapted to measure the second region (22) independently of the measurement of the first region, wherein a common optical element is provided for measuring the first and second regions with the first infrared sensor and a second infrared sensor respectively. Further, the invention concerns an apparatus (100, 200) for contactless measurement of infrared radiation of at least a region of a rail car, wherein the apparatus is adapted to be arranged in a track bed with at least one rail (14a, 14b) and comprises a mounting with an optical element, wherein a measurement module (1000) with an infrared sensor having a directed detection region is fixed to the mounting such that the mounting and the measurement module form a installable unit, wherein the measurement module and the optical element of the mounting have a fixed geometry with respect to each other and have for operation a predetermined relation to each other that is configurable before the installation. |
