Conformal optics for 3D visualization

A novel type of 3D visualization display is presented: a head-mounted projective display (HMPD) with a retro- reflective projection screen conforming to the environment. Application to 3D medical visualization is specifically considered. The imaging concept of the HMPD is modeled and compared to that of a conventional head-mounted display (HMD) for stereo-pair images generation. The HMPD presents several advantages compared to HMDs and other 3D visualization techniques.
