The distance measured by the LiDAR sensor fluctuates even though there is no movement around the lamp

Understanding LiDAR Sensor Distance Fluctuations in Static Environments

If the lamp has the last firmware installed, the distance should vary just a few centimetres every time the measurement is taken. 
This is because the LiDAR sends a laser beam forward and then measures the time it takes for it to return as a way to calculate the distance. The light is reflected via backscattering, as opposed to f. ex. the reflection of a mirror, so it is slightly diffuse – and therefore produces those slight variances.
