Summary: We propose a resolution-preserving passive 2D/3D convertible display using two individual wavelengths. The display employs a holographic optical element to generate and passively separate images at the two wavelengths, creating two viewpoints for each eye. By switching the input image source, the display can convert between 2D and 3D modes while maintaining resolution.

Summary: Glasses-free 3D displays are considered to be the future of the display industry. A flexible liquid crystal micro-lens array (LC MLAs) on a curved PET substrate was developed. An integral imaging-based 2D/3D convertible display system was proposed using the flexible LC MLAs to switch between 2D and 3D modes. The system works in 3D mode when the FLC MLAs have an applied voltage and in 2D mode when the voltage is absent.

Summary: A flicker-reduced time-division light ray quadruplexing technology is proposed to improve the spatial and angular resolutions of 3D images. By optimizing the design of an image-shift optical device and using a 120 Hz 8K projector with a wobbling device and a wavelength-selective plate, high-resolution 3D image display with deeper depth can be achieved.

Summary: A four-mode 2D/3D switchable display using a 1D/2D convertible liquid crystal (LC) lens array is proposed, which can switch between different 3D display effects based on the LC lens array. The LC lens array has low operating voltage, simple fabrication process, and can eliminate moire patterns in the 2D/3D switchable display.

Summary: A new method for axial 3D shape measurement using parallel single-pixel imaging is proposed in this paper, encoding depth through the projection of light transport coefficients and using third-order polynomial fitting for depth mapping and calibration. Experimental results demonstrate that the method can achieve robust, dense reconstruction with high depth accuracy and accuracy.

Summary: This study reports the development and evaluation of a 3D display system for augmented reality-based navigation in automobiles. The system utilizes integral imaging and holographic optical elements to achieve see-through and curved heads-up displays. A novel calibration method using diffusive markers improves calibration accuracy. Although further improvements are needed to meet real-world requirements, the curved and see-through nature of the display screen makes it a good choice for windshield displays.

Summary: This study aims to achieve accurate 3D localization of multiple objects in a complicated scene using passive imaging. An integral imaging system captures the scene from multiple angles and computationally produces blur-based depth information about the objects. The study proposes a method to detect and segment objects in 3D space using integral imaging data obtained from a video camera array, allowing for successful 3D object detection with depth localization.
