The superposition of digital information in the Field of View (FOV) of a user is the basis of the current developments in mixed and augmented reality. Before being studied for near eye device and head mounted display, this application was implemented in Head Up Display (HUD) to help pilots and drivers to manage both the driving stress and the information flow related to the vehicle. Classical optical design of HUD based on the use of a combiner are strongly limited in FOV due to the issues related to pupil management. To overcome this issue head up projection displays have been developed based on the projection of digital image directly on the windshield. To support this approach an efficient projection surface that meets bright reflection and clear transparency has to be developed. We have introduced few years ago an optical approach based on retro-reflective transparent projection surface and a manufacturing process to provide microscopic corner cubes that incorporate an optical diffuser function. We present in this contribution an optimized design that increases the efficiency of the retroreflective structure towards 100%. We also discuss a possible technological process that allows the manufacturing of the master used to replicate the microstructure. This process based on grayscale lithography and on Deep Reactive Ion Etching (DRIE) may guaranty a high retro-reflection efficiency, a high transparency and a realistic draft to allow a molding manufacturing process for the microstructure fabrication.
