SHORT-DISTANCE OPTICAL AMPLIFICATION MODULE AND NEAR-EYE DISPLAY OPTICAL MODULE USING THE SAME |
摘要 |
A short-distance optical amplification module and a near-eye display optical module using the same in the present invention relates to an optical amplification module applicable for short distance and an optical module using the same for near-eye display. The purpose of the present invention is to provide an optical amplification module for large-multiple amplification within a short distance (less than 5cm) and a near-eye display optical module using the same to achieve super large field of view within a short distance (less than 3cm). The short-distance optical amplification module in the present invention comprises a first 45 degree phase delay sheet (2), a partial-transmission and partial-reflection curved lens (4), a second 45 degree phase delay sheet (5) and a reflective polarizing sheet (6) which are sequentially arranged. The near-eye display optical module in the present invention comprises a display screen (1) disposed on the side of the first 45 degree phase delay sheet (2) away from the partial-transmission and partial-reflection curved lens (4). |
