The present invention resolves the drawback of the sensitivity of sensing of the prior optical mouse and inconvenience in use. To achieve the above purpose, the present. invention provides an optical mouse having a dual light source and a method thereof, by increasing the sensitivity. of sensing and the degree of accuracy on various surfaces, such as rough surface or smooth surface, by using a coherent light source and an incoherent light source and adjusting all angles of the assembly of both. Moreover, the present invention provides an automatic switch mode and a manual switch mode to select a required light source. The automatic switch mode switches on the required light source derived from the track pattern sensed on the surfaces.
