1. A sensor system for determining an optical property of a plant by means of a reflection measurement, having a first light source, which emits light along a first beam axis, and a second light source, which emits light along a second beam axis, and at least one first receiver, which is aligned along a third beam axis, to detect light reflected from the plant, wherein the first light source, the second light source, and the at least one first receiver are arranged relative to one another in such a manner that a target cylinder, which respectively extends along the first beam axis and the second beam axis, and a first measuring cylinder, which extends along the third beam axis, at least partially overlap one another in a measuring space, and the first beam axis and the second beam axis respectively enclose an angle with the third beam axis, wherein the first light source emits light in a first wavelength range and the second light source emits light in a second wavelength range, wherein the first wavelength range is a wavelength range of green light, wherein the second wavelength range is a wavelength range of red light, wherein the first light source and the second light source are arranged in a first housing, and the at least one first receiver is arranged in a second housing, and wherein a fastening of the first light source and of the second light source and of the at least one first receiver is provided such that the angles between the beam axes of the light sources and the beam axis of the at least one receiver and a distance between the light sources and the at least one receiver can be adjusted.
