Optical Lens Design for a Virtual Image Projector in a Helmet

摘要

[[abstract]]A projection lens design for a virtual image projector in a helmet is presented. The designed projection lens system shows that optical modulation transfer function (MTF) is 0.55 at the spatial frequency of 40 lp/mm and field of view (FOV) is 8�. In this system, the imaging location is in the front of exit pupil with 1m, and the eye relief in this system is 81 mm.
