  • Publication number: 20210223873
    Abstract: Provided is a pointing device having an optical module for coordinate tracking in order to solve the problem that a pointing device using the diffraction principle of light increases in size due to an optical module, wherein the optical module comprises: a light-emitting unit which irradiates light toward an outside surface; a lens unit provided between the light-emitting unit and the outside surface to refract and diffract the light; and a light receiving unit to which the light reflected from the outside surface through the lens unit reaches, wherein the light receiving unit comprises a detector which senses the reflected light, and a light receiving surface of the detector is inclined at a specific angle toward the optical axis of the light-emitting unit.
