Using threads and a projector, a directional volumetric display capable of moving images and full-color representation was developed in our previous work. However, the horizontal resolution of the directional volumetric display could only achieve 20

The refractive index of a solution correlates closely with its concentration. Estimating the concentration of a solution from its refractive index is an extremely important technique in a wide variety of fields ranging from medicine to food and indus

The light irradiated into a translucent object is multi-reflected inside and then emitted from a position different from the incident position. This behavior is called subsurface scattering. Understanding subsurface scattering behavior is very import

In a previous study, we have developed a directional volumetric display that handles multiple directional images. To realize a multilingual digital signage system, we implement a language identification function on the directional volumetric display.

This paper describes focusing of transmitted and received ultrasonic waves by an acoustic lens based on a phased array. First, we theoretically analyzed the focusing characteristics of the transmitted ultrasonic waves of the phased array. Next, we bu

Although many daily necessities are translucent object, it is difficult to measure the shape of translucent object with traditional 3D scamming approach. We observed the behavior of the light path and proposed the 3D shape measurement method for tran

This paper describes a surface finishing inspection approach for machined metallic surfaces. We focused on an optical reflection property of the machined metallic surface. The optical reflection depends on the material and micro-structure of the obje

This paper describes the new method for measuring the shape of the front surface and the rear surface of a transparent object is difficult because a light does not reflect largely on the surface but mostly penetrate in the object. The proposed use th
