    摘要: A light irradiation device includes a first illumination optical system to emit first light that causes a chemical reaction on an object; a second illumination optical system to emit second light having a wavelength different from a wavelength of the first light; a light emitter to emit the first light from the first illumination optical system and the second light from the second illumination optical system to the object in space shared by the first light and the second light, to irradiate an irradiation area on the object; an image-capturing optical system to capture an image of the space including the object; and circuitry configured to: detect a state of the irradiation area based on the image captured by the image-capturing optical system; and control at least one of the first light and the second light based on the detected state.
