摘要:
An eye projection system is disclosed, including an image generator and an eye projection optical module. The image generator is adapted to obtain data indicative of an image, produce a plurality of light beam portions corresponding to pixels of the image, adjust the intensity of each light beam portion in accordance with a value of a pixel of the image corresponding thereto and direct the light beam portion to propagate along a general optical propagation path towards the eye projection optical module with a projection angle αscn, relative to the general optical propagation path, which is determined in accordance with a location of the respective pixel in the image. The eye projection optical module includes a gaze tracking deflector responsive to input signals indicative of a gaze direction β of a user eye and configured and operable to deflect the general optical propagation path of the light beam portions towards the location of the pupil of the user eye associated with the gaze direction β. The general optical propagation path is deflected such that the light beam portions incident on the pupil with pupil incidence angles αinwith respect to a line of sight of the pupil, where the pupil incidence anglesαincorrespond to the projection angles αscn. The system thereby provides direct projection of the image onto the retina of the eye at a specific location on the retina regardless of the gaze direction β of the eye.揭露一種眼睛投影系統,包含一影像產生器及一眼睛投影光學模組。該影像產生器適用於:取得表示一影像的資料;產生對應該影像的像素的複數光束部分;根據對應各光束部分的該影像的一像素的數值,調整各光束部分的強度;及引導該光束部分沿著一個一般光學傳播路徑以相對於該一般光學傳播路徑的一投影角度αscn朝該眼睛投影光學模組傳播,其中,投影角度αscn係根據在該影像中各別該像素的位置加以決定。該眼睛投影光學模組包含一凝視追蹤偏轉器,其對表示一使用者眼睛的凝視方向β的輸入訊號反應,且建構成可操作用以偏轉該等光束部分的該一般光學傳播路徑朝向與該凝視方向β相關聯的該使用者眼睛的瞳孔的位置。該一般光學傳播路徑係被偏轉,使得相對於該瞳孔的視線,該等光束部分以瞳孔入射角αin入射該瞳孔,其中瞳孔入射角αin係對應投影角度αscn。藉此無論眼睛的該凝視角度β,該系統將該影像於該眼睛的網膜的一特定位置直接投影於該網膜上。
