  • Publication number: 20210247516
    Abstract: An optical navigation apparatus including a plurality of light sources, a sensing element, and a control circuit is provided. The plurality of light sources are configured to emit a plurality of light beams onto a surface under measurement, and the plurality of light beams are incident on different positions of the surface under measurement to form a plurality of areas under measurement. The sensing element is configured to receive a plurality of reflected light beams after the plurality of light beams are reflected by the surface under measurement. The control circuit is electrically connected to the plurality of light sources and the sensing element. Each of the plurality of reflected light beams forms a sensing image. The control circuit calculates a movement trajectory of the optical navigation apparatus through a correlation of the plurality of sensing images over a plurality of different times.
