“…Three-dimensional (3-D) imaging plays a key role in 3-D techniques. Also, their application fields are very broad such as augmented reality, autonomous driving, entertainment, defense, and biomedical imaging [ 1 , 2 , 3 , 4 , 5 , 6 ]. The main components of a 3-D imaging system are divided into 3-D image acquisition, 3-D image processing, and 3-D visualization.…”

This paper describes a computational 3-D imaging system based on diffraction grating imaging with laser sources of multiple wavelengths. It was proven that a diffraction grating imaging system works well as a 3-D imaging system in our previous studies. The diffraction grating imaging system has advantages such as no spherical aberration and a low-cost system, compared with the well-known 3-D imaging systems based on a lens array or a camera array. However, a diffraction grating imaging system still suffers from noises, artifacts, and blurring due to the diffraction nature and illumination of single wavelength lasers. In this paper, we propose a diffraction grating imaging system with multiple wavelengths to overcome these problems. The proposed imaging system can produce multiple volumes through multiple laser illuminators with different wavelengths. Integration of these volumes can reduce noises, artifacts, and blurring in grating imaging since the original signals of 3-D objects inside these volumes are integrated by our computational reconstruction method. To apply the multiple wavelength system to a diffraction grating imaging system efficiently, we analyze the effects on the system parameters such as spatial periods and parallax angles for different wavelengths. A computational 3-D imaging system based on the analysis is proposed to enhance the image quality in diffraction grating imaging. Optical experiments with three-wavelength lasers are conducted to evaluate the proposed system. The results indicate that our diffraction grating imaging system is superior to the existing method.

“…Moreover, it can provide quasi‐continuous viewpoints and full parallax information 4,5 . Integral imaging has shown great potential applications in many fields, such as commercial electronics, entertainment, manufacturing, autonomous driving, augmented reality, and so on 6 . However, it also has certain limitations in terms of display performance, specifically, small viewing angle, low resolution, and narrow depth of field (DOF) 5,7 .…”

In this paper, we propose a depth‐enhanced integral imaging display based on bifocal lens array. The bifocal lens array consists of a small lens array with plano‐convex circular lens units and a large lens array with square lens units. The proposed display device generates two central depth planes and stitches two reconstructed 3‐D images in depth, which largely improves the depth of field. The experimental results indicate that the proposed structure reconstructed 3‐D image with the depth of field as large as 150.8 mm, which is double of conventional integral imaging display.

“…The real 3D display systems of various types, including integral imaging and holographic and multi-view methods are available at present [1][2][3]. In [4], a detailed overview of some studies in the field of integral imaging, including sensing of 3D scenes, processing of captured information, and 3D display and visualization of information is presented. Integral imaging has significant advantages over other methods, namely, the absence of a complex mechanical and optical system, the use of inexpensive materials in production, and the possibility of simultaneous vision by several viewers.…”

Glassless 3D displays using projectors and mobile phones based on integral imaging technology have been developed. Three-dimensional image files are created from the 2D images captured by a conventional camera. Large size 3D images using four HD and Ultra HD 4K projectors are created with a viewing angle of 35 degrees and a large depth. Three-dimensional images are demonstrated using optimized lenticular lenses and mobile smartphones, such as LG and Samsung with resolution 2560 × 1440, and 4K Sony with resolution 3840 × 2160.
