Liquid Refractive Index Measurement Based on Inverse Raytracing Using an Optical Angle Sensor
Autor: Kozo Ohtani, Mitsuru Baba
Publikováno v: 2019 12th Biomedical Engineering International Conference (BMEiCON).
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

Light scattering analysis for measuring the 3-D shape of a translucent object
Autor: Kozo Ohtani, Mitsuru Baba
Publikováno v: SICE
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

Improvement of focusing of transmitted and received ultrasonic waves by a phased array acoustic lens
Autor: Kozo Ohtani, Takahiro Ugajin, Mitsuru Baba
Publikováno v: 2017 56th Annual Conference of the Society of Instrument and Control Engineers of Japan (SICE).
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

Surface finishing inspection using a fisheye camera system
Autor: Kozo Ohtani, Naoya Kogumasaka, Mitsuru Baba
Publikováno v: 2017 56th Annual Conference of the Society of Instrument and Control Engineers of Japan (SICE).
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

Evaluation of Surface Shape and Refractive Index of a Transparent Plate Based on Light Path Analysis
Autor: Taiki Okazaki, Mitsuru Baba, Kozo Ohtani
Publikováno v: Applied Mechanics and Materials. 36:458-465
Many practical tasks in industry require the simultaneous determination of 3-D shape and refractive index of a transparent object. We have formulated an approach to evaluating the surface shape and refractive index by light path analysis. The effecti
