Compact and low-cost devices are needed for autonomous driving to image and measure distances to objects 360-degree around. We have been developing an omnidirectional stereo camera exploiting two hyperbolic mirrors and a single set of a lens and sens

Remote visual testing by video cameras is the standard process for inspecting the pressure vessel of nuclear reactors. The inspectors need to find stress corrosion cracking of around several tens of µm wide on a display monitor observed by remote wi

A Fresnel Zone Aperture (FZA) mask for a lensless camera, an ultra-thin and functional computational imaging system, is beneficial because the FZA pattern makes it easy to model the imaging process and reconstruct captured images through a simple and

As part of our ongoing research on lensless imaging with a Fresnel zone aperture (FZA), we propose a method for optimizing the configuration of the FZA, which reflects the influence of the diffraction of its shadow, and the sensitivity characteristic

For autonomous driving, we propose an omnidirectional three-dimensional sensing and viewing system employing monocular stereo camera which has both ranging and recognition function. In this system, four monocular stereo cameras, which are located at

Lensless light-field imaging with Fresnel zone aperture (FZA) is a technology that enables lensless cameras with beneficial features such as light calculation load in the image reconstruction processing, and refocusing, i.e. post-capturing focus adju
