摘要 |
An optical detection device includes: a light source unit that emits source light; a curve-shaped light guide that includes: a light incident surface to which the source light is incident, the light incident surface being located in an end portion of the light guide; and a convex surface from which the source light received by the light incident surface is output; an emitting direction setting unit that receives the source light output from the convex surface of the light guide and sets an emitting direction of emitting light to a direction of a normal line of the convex surface; a light receiving unit that receives reflection light acquired by reflecting the emitting light off an object; and a detection unit that detects at least a direction in which the object is located based on the light reception in the light receiving unit.
