Adding nano-particles with high refractive index can greatly improve the optical properties of the PMMA-based composites, which were developed as the new-type rear projection screen. In this paper, the influence on the optical properties, such as gain and view angle, by the content of additive TiO2 nano-particle was studied. Curves of optical properties versus content of nano-particle were obtained and the rational factors were found. Finally the reasons were discussed from the nanostructure point of view and the scattering principle.

Wide Field Of View

The teleoperation of construction machinery has been introduced to mines and disaster sites. However, the work efficiency of teleoperations is lower than that of onboard operations owing to limitations in the viewing angle and insufficient depth information. To solve these problems and realize effective teleoperations, the Komatsu MIRAI Construction Equipment Cooperative Research Center is developing the next-generation teleoperation cockpit. In this study, we develop a display for teleoperations with a wide field-of-view, a portable projection screen, and a system that reproduces motion parallax, which is suitable for depth perception in the operating range of construction machinery.
