Abstract: A light detection sensor 10 comprises a light source 12 for radiating light to a detection object T and a light receiver 11 comprising a plurality of detectors for detecting intensity of light from the detection object T. The plurality of detectors comprises at least, a first detector 11a for detecting intensity of light of a first wavelength band, and a second detector 11b for detecting intensity of light of a second wavelength band different from the first wavelength band. Sensitivity of the first detector 11a to the light of the first wavelength band is lower than sensitivity of the second detector 11b to the light of the second wavelength band. A light receiving area of the first detector 11a is larger than a light receiving area of the second detector 11b.

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.
