| 摘要 |
<p>The invention relates to a sensor system (10) for determining an optical property, in particular the chlorophyll content, of a leaf disease or a pest infestation of a plant (12) by means of reflection measurement, having a first light source (14) emitting light along a first beam axis (16) and a second light source (18) emitting light along a second beam axis (20), and at least one receiver (22) aligned along a third beam axis (24) in order to capture light reflected by the plant (12). The first light source (14), the second light source (18), and the at least one first receiver (22) are further disposed relative to each other such that a target cylinder (26, 26') running along each of the first beam axis (16) and the second beam axis (20), and a first measurement cylinder (28) running along the third beam axis (24) at least partially overlap each other in a measurement space (58) and the first beam axis (16) and the second beam axis (20) each enclose an angle (a,d) with the third beam axis (24). The invention further relates to a corresponding method for determining an optical property of a plant (12) by means of a reflection measurement, and further to a method for analyzing a measurement for determining an optical property of a plant.</p> |
