Abstract
A generator and a method for generating far infrared polarized light are related. The generator includes a far infrared light source configured to emit a far infrared light; a polarizer located on a light emitting surface of the far infrared light source, wherein the polarizer includes a carbon nanotube structure including a plurality of carbon nanotubes arranged substantially along the same direction, and the far infrared light passes through the polarizer to form a far infrared polarized light; and a heater configured to heat the carbon nanotube structure. The method includes allowing the far infrared to pass through the carbon nanotube structure and heating the carbon nanotube structure as the far infrared passes through the carbon nanotube structure.
