• Head-mounted display
• FFRM
• Two ellipsoids structure

A new method to design a low distortion, even relative illumination, optical see-through head-mounted display (FWD) with a freeform reflective mirror (FFRM) based on the two similar ellipsoids structure is proposed. The HMD we have realized has a simple structure which consists of two similar ellipsoid surfaces, an FFRM, a 7-piece co-axis relay lens, and an OLED. This structure can be applied to offset distortion, reach even relative illumination, and correct the off-axis aberrations. The HMD we finally have realized has a near 3% low distortion, a higher than 80% relative illumination, and a 40 degrees x30 degrees field of view (FOV).
