Hi,
I'd like to measure an angular displacment position with 0.1 degree accuracy. The machine has a shaft encoder but I'd like to measure in another more accurate one so to check the accuracy of the shaft encoder too.
To reach it, an idea is to use a laser beam where the gun is connected to the machine and then measure the displacement of the beam on a screen on, say, 18 meters from the source (roughly 3 cm displacement is equal to 0.1
degree). But we have not any laser instrument and it is expensicve. Any other idea?
Thanks
