Characterization of the Optical Properties of 2D-to-3D Conversion Imaging Screens Using Bidirectional Transmittance Distribution Function

Abstract

We have recently developed screens made of nanomaterial-coated translucent sheets. In these screens, 2D picture images projected on the screen can be transformed automatically into 3D images with stereoscopic backgrounds. The 2D-to-3D transformation is considered to be based on the analogous mechanism that we feel the depth when we see human skin. One of our typical imaging screens consists of three layers made of an aluminum-deposited sheet and two translucent sheets which are coated with titanium dioxide nanoparticles. In this present work, these translucent sheets have been intensively characterized with respect to their optical properties using a CCBTDF instrument. The CCBTDF measurement suggest that the blue light with the short wavelength is scattered on the surface of the first layer, while the red light with the long wavelength permeates to the under layers. We have confirmed that our screen has the analogous optical mechanism of human skin in terms of the color dependence.
