Abstract

The present invention relates to a method for detecting accumulation of material (201) on a blade (108a) of a wind turbine (104), said method comprising the steps of: transmitting (S1) a light beam towards the blades (108a - 108c) of said wind turbine (104); receiving (S2) reflected light from the blades (108a - 108c) of said wind turbine(104); determining (S3) an instant width of said blade (108a) based on a detected intensity variation over time of the reflected light; and providing (S4) a signal indicating accumulation of material (201) on said blade (108a) if said determined width of the blade (108a) based on the detected intensity over time is larger than a known width of the blade (108a) without accumulation of material (201).
