Projection system for optical display device e.g. head-mounted display, has modification lens provided for enlarging or multiplying exit pupil, where modification lens is arranged in path of rays before intermediate image plane

摘要

The system (16) has an image generation device (18) generating an image (20) in an intermediate image plane (40). A projection lens (22) with an exit pupil (22a) produces a picture of the image, where the picture is removable by an user. A modification lens (46) enlarges or multiplies the exit pupil so that the picture is an enlargement or multiplication of the produced image. The modification lens is arranged in path of rays before the intermediate image plane. A laser scanner (28) is provided in the image generation device.
