ABSTRACT:
An illumination light receiver includes: a wavelength separation mechanism separating visible light containing optical signal data distributed among wavelengths corresponding to three primary colors into the wavelengths corresponding to the three primary colors; a dispersion restraining mechanism restraining dispersion of light outputted from the wavelength separation mechanism; and a light receiving portion illuminated, separately for each of the separated wavelengths corresponding to the three primary colors, by the light outputted from the dispersion restraining mechanism, the light receiving portion converting the optical signal data into and extracting an electrical signal.
