An Automatic Moving Stage with Bar Mechanism in Optical Microscope

This paper investigates an automatic moving stage with parallelogram linkage mechanism in optical microscope. The formula of the moving stage position related to driving motor rotational angular is presented, a regular available region of the moving stage is obtained, effects of system parameters on the available region size and positioning accuracy are studied, and a design method for this automatic moving stage with bar mechanism is indicated. This paper presents a research foundation for the high-accuracy and low-cost auto-control of the moving stage in optical microscope.
