    Abstract: The present disclosure illustrates an optical navigation chip. The optical navigation chip is disposed on an optical navigation module. The optical navigation module includes a light-emitting unit. The light-emitting unit provides a light beam to irradiate a surface of a displacement generating unit. The light beam has a low divergence angle to reduce scattering. The optical navigation chip includes a sensing array and a displacement calculating unit. The sensing array is disposed corresponding to the surface. The sensing array receives a reflected light beam which the surface reflects, and captures an image once every capturing interval based upon the reflected light beam. The displacement calculating unit calculates a relative displacement between the optical navigation chip and the surface according to the images.
