Accuracy evaluation of two-dimensional straightness measurement method based on optical meter

Abstract

The article analyses the accuracy evaluation of non-contact optical mechatronic two dimensional devices for straightness measuring. Measurement principles of the device are based on the evaluation of the position from the phase difference of two signals where one of them is generated by a non-movable photodiode, acting as a reference source, and the other one is attached to the moveable part of the technological machine. The device can be used for measurement, diagnosis and accuracy testing of mechatronic devices, robotics and technological machines.
