Abstract
A light detection device includes a diffraction element and a light detection element. The diffraction element diffracts a beam of light that is incident on the diffraction element. The light detection element includes light receivers to receive diffracted light. The diffraction element generates beams of the diffracted light by dividing the beam of light. The light detection element determines a displacement of the beam of light relative to the diffraction element on the basis of quantities of light of the beams of the diffracted light. The light detection element determines an angle change of the beam of light relative to the diffraction element by dividing the quantity of light of one of the beams of the diffracted light.
