The design and applications of automatic counter for Michelson interferometer are presented. The photoconductive re?sistance and thresholds comparator are used in the device to collect the interference stripes, producing the electric impulses corre?sponding to the light and dark stripes. The electric impulses are counted and displayed by the microcontrollers. The device for the experiment has a simply structure, good accuracy and may leave the operator from trivial counting works. Based on the data of experiment, problems of manual count can be solved, measurement error be reduced, thus the accuracy of the experiment im?proved.
