An electronic device, comprising: a first light source, configured to emit first light; a second light source, configured to emit second light; a first optical sensor, configured to sense first optical data generated based on reflected light of the first light; a light guiding device, configured to receive the second light; and a second optical sensor, configured to sense second optical data generated based on the second light emitted by the light guiding device. The first optical sensor and the second optical sensor can be integrated to a single optical sensor.

Electronic device which can determine a dirtiness level

An optical detection device includes a first linear light source, a second linear light source, an optical sensor array and a processor. The first linear light source is adapted to project a first long strip illumination beam onto the target container. The second linear light source is adapted to project a second long strip illumination beam onto the target container, and the second long strip illumination beam is crossed with the first long strip illumination beam. The optical sensor array is adapted to receive a first long strip detection beam and a second long strip detection beam reflected from the target container. The processor is electrically connected to the optical sensor array. The processor is adapted to analyze intensity distribution of the first long strip detection beam and the second long strip detection beam to acquire a relative distance between the optical sensor array and the target container.
