SHORT-DISTANCE OPTICAL AMPLIFIER MODULE, AMPLIFICATION METHOD AND AMPLIFICATION SYSTEM

WIPO Patent Application WO/2017/128187

A1

Provided are a short-distance optical amplifier module, a short-distance optical amplification method and a short-distance optical amplification system. The module comprises a reflective polarizer (1), a first phase retarder (2), an imaging lens (3), a second phase retarder (4) and an absorptive polarizer (5) arranged in sequence. The reflective polarizer (1) is arranged in a transmission path of an optical image. The first phase retarder (2) is arranged in the transmission path of the optical image penetrating through the reflective retarder (1). The imaging lens (3) is arranged in the transmission path of the optical image. The second phase retarder (4) is used for converting the polarization direction of the optical image from an elliptical or circular polarization direction to a second linear polarization direction. The absorptive polarizer (5) is arranged on one side, away from the imaging lens (3), of the second phase retarder (4). The short-distance optical amplifier module makes light first reflected and finally refracted. Since there is no light loss in the reflection, a light loss resulting from chromatic dispersion of refracted light caused by first refraction and then reflection in an existing short-distance optical amplifier module, thereby affecting the light quality, is avoided.
