As examples of a well-known 3D display system, there are 3D films. Observer usually needs to use glasses such as polarized light filter, shutter, etc. Using glasses methods are provided not only in theaters but also in house. However, they are troublesome because the user must put on glass. Therefore, glass-free 3D display systems are receiving attention. Our laboratory develops the 3D display using holographic optical element array screen. However, it is created by hand. Handmade screens are not reproducibility and reality because the screen need too much holographic optical elements and manual adjustment change its performance. The purpose of this study is to automate the process
