Design of Projection Lens for Head-Mounted Displays under Eye Model and the Optical Assessment in Visual Space
The optical assessment of head-mounted projection displays in visual space was further consummated. An eye model which was closer to the actual situation was used to simulate the human eye in order to give a detailed assessment of the projection lens. A further guidance on the design of projection lens from the imaging results of eye model was also carried on. The results showed modulation transfer function both on the zero and full field of view was good; on zero field of view, the minimum angular resolution of human eye was 1′, and on full field of view, the acuity determined by single-pixel of micro-display was achieved, so the system could completely satisfy the usability in head-mounted projective displays. Maximal distortion was less than 5%, and lateral color was unable to affect the angular resolution of human eye.
