I assume the laser gun rotates but in my experience the rebound will not be strong enough if the target surface is not at right angles to the ray. How does it work?
The laser device does indeed rotate (it has its own inbuilt motor and rotates itself – having received a command from the laptop). I agree that extreme acute angles will at some point give a false reading if not catered for – in these instances the user can easily help the laser beam by holding a small item like a piece of card or paper to assist the beam (if really acute angles!) however these cases (from our testing) have been quite rare, angles of a couple of degrees can still be taken without any intervention required. The biggest problem we have found is black surfaces (mainly glossy ones like black plastic drainpipes) – these would need a bit of masking tape just to help the reflection of the beam – but that’s the only big problem we have had with surfaces! Before taking a scan of a room it would also be prudent to see if moving the tripod and device to the optimum position within the room would alleviates any acute angle issues beforehand.. Our system, being radio controlled fro
