Circularly polarized light - separation film, method for producing a circularly polarized light - separately ion film, infrared - sensor and the scanning system and the sampling method with the use of light

摘要

This invention, on: a circularly polarized light - separation film, of the selectively the transmission of any one of the right - which is circularly polarized light and to the left - which is circularly polarized light in at least a part of a the near infrared - light waves lengths area and a baffle layer for visible light, the light in at least a part of a wavelength range for visible light is reflected or absorbed, and a circularly polarized light - separation layer that facilitates selectively the transmission of any one of the right - which is circularly polarized light and to the left - which is circularly polarized light in at least a part of a wavelength of the near infrared light; a manufacturing process for the circularly polarized light - separation film; an infrared - sensor, comprising the circularly polarized light - separation film; and a scanning system and a sampling method with the use of the circularly polarized light - separately ion film or a combination of the circularly polarized light - separation film and a film comprising the visible light - baffle layer. The scanning system and the sampling method result in a high sensitivity independent of the environment, and causes a lower scanning errors.
