摘要：
We propose a flicker-reduced time-division light ray quadruplexing technology to improve both the spatial and angular resolutions of three-dimensional (3D) images. The proposed method uses an image-shift optical device with polarization gratings. By optimizing the design of the image-shift optical device and incorporating it into the display system, we confirmed that the resolution characteristics of 3D images displayed at a depth of 30 mm or more can be improved by up to 1.58 times. Furthermore, by developing the display system using a 120 Hz 8K projector with wobbling device and a wavelength-selective lambda/2 plate for reducing flicker, we achieved high-resolution 3D image display with deeper depth.
