By performing parameter refining on the f 3 that influences the optical amplification effect, the module can keep a small overall thickness while obtaining a large optical amplification effect and it can be applied in a small-size VR device, so that the VR device can realize a wide field angle, a large eyebox and high-quality imaging effect, and hence a better user experience.

摘要： Disclosed are a short-distance optical amplification module, a short-distance optical amplification method and a short-distance optical amplification system. The module comprises a reflective type polarizing plate (1), a first phase delay plate (2), an imaging lens (3), a second phase delay plate (4) and an absorptive type polarizing plate (5) that are arranged successively. The reflective type polarizing plate (1) is arranged on a transmission path of an optical image. The first phase delay plate (2) is arranged on the transmission path of the optical image passing through the reflective delay plate (1). The imaging lens (3) is arranged on the transmission path of the optical image. The second phase delay plate (4) is configured for converting a polarization direction of the optical image from an elliptical or circular polarization direction to a second linear polarization direction. The absorptive type polarizing plate (5) is arranged on one side of the second phase delay plate (4) that faces away from the imaging lens (3). By the short-distance optical amplification module of the invention, light is reflected first and refracted finally. Because 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 amplification module may be avoided, thereby preventing the light quality from being affected.

摘要： Disclosed are a short-distance optical amplification module, an amplification method and an amplification system. The module comprises a first phase delay plate (2), an imaging lens (4), a second phase delay plate (5) and a reflective type polarizing plate (6), wherein the first phase delay plate (2) is arranged in a transmission path of an optical image having a first linear polarization direction, the imaging lens (4) is arranged in a transmission path of an optical image having an elliptical or circular polarization direction, and the second phase delay plate (5) is arranged on one side of a second optical surface of the imaging lens. A second linear polarization direction is orthogonal to the first linear polarization direction. By means of the first phase delay plate (2), the imaging lens (4), the second phase delay plate (5) and the reflective type polarizing plate (6), an optical image is reflected by the reflective type polarizing plate (6) on a transmission path, and then is amplified on the imaging lens (4). Thus, not only the optical image can meet the requirement of optical magnification, but also the second phase delay plate (5) and the reflective type polarizing plate (6) can be arranged to adhere to each other, thereby further reducing the size and volume of an optical module.
