Abstract

In order to meet the requirement of lightweight and small size, we design an avionic helmet mounted displays (HMDs), using freeform surface described by Gaussian radial basis function. An off-axis see-through wide field of view HMD system with a 100mm eye relief, 15mm pupil, 45°×32° FOV is achieved. The design result shows that the optical system of HMDs has low aberration, and can provide user clear symbol or video images. Furthermore, we try a new way to determine a starting point of optimization quickly while designing.
