Abstract
A light detection sensorcomprises a light sourcefor radiating light to a detection object T and a light receivercomprising a plurality of detectors for detecting intensity of light from the detection object T. The plurality of detectors comprises at least, a first detectorfor detecting intensity of light of a first wavelength band, and a second detectorfor detecting intensity of light of a second wavelength band different from the first wavelength band. Sensitivity of the first detectorto the light of the first wavelength band is lower than sensitivity of the second detectorto the light of the second wavelength band. A light receiving area of the first detectoris larger than a light receiving area of the second detector
