摘要： An optical navigation module for receiving control from an object is provided. The optical navigation module includes a module surface above which the object is disposed; a light source located under the module surface and configured to project a first cone of light to the object along a first optical axis through a first optical construction; and a light sensor located under the module surface and configured to detect a second cone of light that is resulted from the first cone of light being reflected by the object along a second optical axis through a second optical construction, and thereby to collect a spatial intensity profile of the reflected light. The intersection of the first optical axis and the second optical axis is below the module surface.
