Abstract
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 5 cm) and a near-eye display optical module using the same to achieve super large field of view within a short distance (less than 3 cm). The short-distance optical amplification module in the present invention comprises a first 45 degree phase delay sheet (), a partial-transmission and partial-reflection curved lens (), a second 45 degree phase delay sheet () and a reflective polarizing sheet () which are sequentially arranged. The near-eye display optical module in the present invention comprises a display screen () disposed on the side of the first 45 degree phase delay sheet () away from the partial-transmission and partial-reflection curved lens ().
