Abstract:The purpose of this project is to increase the measurement accuracy of the rotation angle and
measurement speed. There is one rotatable circular plane with many holes in it, the initial
location of this circular plane is stored in a CCD camera and is regarded as a stationary
circular plane. When the rotatable circular plane is rotated, the intensity of the light across
the holes of two circular planes is changed. This intensity will represent the position of the
rotatable circular plane, so the position of tha… Show more
