Abstract
A light detection sensor includes a light source that irradiates a detection target with light, a rod lens that collects emitted light from the detection target, a first light receiving element that detects the emitted light that has passed through the rod lens, and a second light receiving element that detects the emitted light that has passed through the rod lens, at a position different from a position at which the first light receiving element detects the light.
