The invention relates to a method for monitoring a mirror comprising a first stack containing a first layer (14), a reflective second layer (10) having first and second opposite faces, the first face reflecting light and the first layer covering the second face, and a third layer (12) that is transparent to solar radiation, which third layer (12) is formed on the first face, the method comprising the following steps: measuring (32) the colour of the first layer (14); and analysing (34, 36, 38) variations in said measurement in order to characterise the degradation of the second layer (10). |
