Paper is non-uniform; thus, it is difficult to ascertain whether the slight differences in near-infrared absorption spectra are caused by the difference in paper type or the paper’s non-uniformity. We used near-infrared hyperspectral imaging to mea

Clinical and Preclinical Optical Diagnostics II.
We propose an ultrasonic-assisted point-one-shot mid-infrared Fourier spectroscopy device involving an ultrasonic liquid-cell and point-one-shot Fourier spectroscopy (diameter: 6 mm, thickness: 5 mm) for ear clip type non-invasive blood glucose senso

A mid-infrared spectroscopic imager needs to be portable and tough for the identification of dyestuffs used for murals in ancient tombs during archaeological on-site analysis. Meanwhile, an extremely compact and tough hyperspectral camera with mass l

Optical Diagnostics and Sensing XIX: Toward Point-of-Care Diagnostics.
For monitoring and prevention of lifestyle diseases, we have investigated development of non-invasive ear-clip type blood glucose sensors that can be used by individuals in daily life. Because mid-infrared light (λ = 8–14 μm) is absorbed strongly

We propose the point one-shot mid-infrared Fourier spectroscopic imager, which is composed of only a single Ge lens (diameter: 6 mm; thickness: 5 mm) and a two-dimensional array device. The lens is a nonspherical lens on the front side and a dual-axi

Application of spectroscopic techniques to suspensions is difficult because optical scattering caused by solid particles reduces the accuracy. At the extreme, dense suspensions like blood cannot be analyzed by spectroscopic techniques. In the present

Any plant species may be distinguished from only two basic spectroscopic data obtained by the orthogonal polarized light illumination method. We demonstrate its viability by obtaining separately the near-surface and internal-reflected light from plan

We developed the palm-size 2-dimensional type and beans-size 1-dimensional type spectroscopic imager, so-called hyperspectral camera, for environmental measurements. To visualize broad-area plankton or chlorophyll distributions using drones or nano-s

We propose to monitor blood glucose concentrations using mid-infrared spectroscopy in an ultrasonic-assisted liquid cell that can be attached to a dialyzer. This method can measure the transmitted light through whole blood during dialysis.
