    摘要: In an apparatus and a method for performing communication by using polarization property of light, a transmission apparatus includes a controller to establish a first channel corresponding to a first polarization property; a signal encoder to encode data into an electrical signal; a light emitting unit to emit light based on the electrical signal; and a polarizer to polarize the light into first polarized light having the first polarization property, and to output the first polarized light. A reception apparatus includes a controller to establish a first channel corresponding to a first polarization property; an analyzer to receive light, and to extract first polarized light having the first polarization property from the light; a polarized light receiver to convert the first polarized light to an electrical signal; and a signal decoder to decode the electrical signal to digital data.
