Abstract

Based on the requirements of the modern head-mounted display on the image quality, distortion, size and weight, we design a diffractive-refractive objective lens for the head-mounted projective display with the field of view of 50 degree, exit pupil diameter of 10mm, effective focal length of 20mm and 1.3 inch micro-display. It is shown that the designed optical system, comparing with the traditional ones, has smaller size, lighter weight and compacter structure with better aberrations performance. With the other unique properties such as the ability of allowing correct occlusion of real and virtual objects in augmented environments, the depth perception of the objects in real scene, independent viewpoints and no crosstalk in multi-user environments, the designed system has a potential applications in collaborative environments, wearable computers and visualization training.
