I am working with SICK lidars and have to mount/unmount them quite often on my robot. The mounting process is very tedious especially when it comes to making sure that the lidars are horizontal. I thought about using IR goggles (like the night vision ones) and some fog machine (like the one in nightclubs) in order to see the surface covered by the lidar's rotating laser ray. As a result I would expect to see something like this but planar.
Before thinking about trying to get my hands on such hardware I wanted to ask:
Do sick laser have enough intensity to be observed by such goggles? Does anybody tried such an approach?
