Abstract
An optical detection device includes: an optical sensor configured to detect light from a light source of an indication lamp; an optical-detection-side communication unit configured to wirelessly transmit at least an optical detection signal of the optical sensor; and a photoelectric conversion unit configured to convert light from the light source into power and to store the power. The optical sensor and the optical-detection-side communication unit operate using the power stored in the photoelectric conversion unit.
