| Outline of Final Research Achievements |
Curved light field 3D displays were developed and tested. An animated 3D-scene of size 20cm x 10cm x 5cm (depth) can be successfully viewed in 3D using naked eye for a viewing angle of 10-degrees. The display system is very simple and consists of only a commercial projector and holographic micro-lens array sheet (fabricated by us). The key achievements are 1) development of a fully automatic calibration method that can be used by any one, 2) printing holographic lens array sheet as a curved screen using home-grown printing system, 3) new algorithm for computing data to be displayed on the 2D projector from a 3D-scene.

| Academic Significance and Societal Importance of the Research Achievements |
The developed flexible 3D display requires only a 2D projector, a special micro-lens sheet and computed 3d scene data. The user can view the 3D scene of size 20cm x 10cm x 5cm(depth) without technical skill. It can be used as 3D head-up displays in car wind shield, home windows (smart windows) etc.
