Please help me to find a sensor with a narrow beam, can be a transmitter and receiver type, to measure distance with accuracy of mm, between 2 points with a range between 10 mm to 300 mm, working in a linear clean environment. I needed to correct, from time to time, drift cause by missing steps of a stepper motor in a actuator type linear system.
I could buy a lidar-lite v3, or something like this time of flight sensor, but I think given the nature of the machine - not moving, just linear motion in a clean environment, maybe I can find something more quick and precise, with a transmitter and receiver, and why not cheaper. Speed is important the movement is around 10 m/s.
All suggestion are welcome. :) :) :)
