The image sensor ”BT3300N” for high-resolution 8K super-high vision camera, which has 16 times as many pixels as the current high-definition TV broadcasting standard, was manufactured by Brookman Technology Inc.

BT3300N was developed as a reference of the only (as of January 2016) image sensor achieving the full-specification standard of the Super Hi-Vision (8K, 120 frames/second). Cameras using this has been already developed in the related companies and applied to the broadcast test in NHK.

Toccare, the new Near Infrared Spectroscopy (NIRS) was developed jointly by Hamamatsu Medical College, Shizuoka University, and ASTEM Inc.

Masashi Niwayama, associate professor of Shizuoka University, who has performed analysis and measurement of various light propagation, successfully reduced the measurement error, which has been long-time problem, to about 1/10 with the special decomposition method by multiple-point optical measurement and principle of NIRS.
This is a technology to measure the distribution of blood O2 content in depth direction precisely with special decomposition method.

Professor Naohiro Kanayama, Hamamatsu Medical College, has proposed the concept of integrated this NIRS sensor with fingers of the doctor. Owing to this, it has become possible to diagnose the health information of fetus and newborn babies.

With difference frequency method, which utilizes GaP crystalline, single-color coherent terahertz light source is developed. Its application to terahertz laser spectrophotometry devices is being progressed.
This compact high-power terahertz light source, which was made compact and energy-saving so that it could be incorporated in the inspection process of factories, etc. as a way of application in industries, was developed as a device for everyone to handle easily.

Dr. Sakamoto of National Institute of Health Sciences investigated the influence of binder to the transition of pseudo-crystalline form and currently is engaged in evaluating the relation between the viscosity of binder, which is important additive in preparing granule for tableting, and pseudo-transition of crystalline form in cooperation with Professor Sasaki. It has potential to lead to the detection of quality error based on the physical properties such as dissolution behavior, etc. It might unlock the potential of terahertz wave technology and enable to investigate the distribution of pseudo-crystalline form and transmission processes.
Hereafter, it was shown that this technology can be utilized in not only the evaluation of the quality properties in the R & D phase of tablets, but also be applied to quality assurance in the process as well as troubleshooting in case of unpredicted risk.

Time of Flight method is one of distance image measurement methods which use an image sensor. It is the method to measure the distance L to the object by projecting light on the object and measuring the time for the reflection to return.

• Speed of the Light: 30 thousand kilometer per second (299,792,458m / sec)
• Time for the light to proceed 1m: 3.3 nanosecond (＝3.3×10^-9 s)
• Time for the light to proceed 1mm: 3.3 picosecond (=3.3×10^-12 s)

Kawahito/Kagawa/Yasutomi Laboratory of Shizuoka University
Kawahito, Kagawa, Yasutomi Laboratory, which is developing TOF Distance Image Sensors, has realized charge transport by CMOS process with almost as fast as by CCD and realized the measurement of the distance to the object. The CMOS-TOF camera with this image sensor installed can check light-dark image and distance image.

Image sensors are, simply speaking, guts of digital cameras. Image sensors are one of the industrial fields Japan is most strong in, with more than 95% of CCD and more than 50% of CMOS developed in Japan. Existing high sensitivity cameras had a problem in size and weight, because they need cooling (-50℃) and driven with high voltage (30V).

In Kawahito-Kagawa-Yasutomi Laboratory of Shizuoka University, it was enabled to shoot both dark and light places at the same time, with the dynamic range as much as 150dB, higher than that of human eyes.
As a consequence, they were successfully downsized in the joint development with a company.

Since existing color cameras has the color gamut limited within the triangular area of the sRGB, they adapt the color so that the actual color data may be expressed more beautifully.

PaPaLab’s cameras can record colors which could not be photographed before, with the camera filter given sensitivity of human eyes. They can shoot “just what you see.”

Additionally, this camera, which measures all color visible for human, colorimetrically, can be used as a measuring device to analyze colors with high precision.

Hamamatsu Photonics calls R & D activities along the value complying “sustainability” “Life Photonics.” It is engaged in the study of various optical technologies with the theme related to “Life,” which includes various meanings such as life, living creatures, human life, source of vitality, and ways of life.

Positron (positive electron) which was emitted from the positron-emitting nuclide which was incorporated in an organism, after losing kinetic energy in the neighborhood, combine with electron composing material and extinguishes. At that time, a pair of gamma rays (with energy of 511 keV) emitted to direction opposite to each other. The position where the positron was emitted is detected by simultaneously detecting the pair of gamma rays with a pair of detectors.

Dr. Masashi Niwayama, associate professor at Shizuoka University, has made NIRS, which was very large device, compact and developed a new algorithm to measure hemodynamics in the bio-tissue non-invasively, by detecting light penetrating through the body with multiple photodetectors with different distance.

The NIRS system, which uses the new special resolution method, has improved the measurement precision by correcting the influence of tissues lying between, such as skin. Additionally, its accuracy has been confirmed by comparing it with the conventional positron CT by experiments.

This brain NIRS of sun visor type is the implementation of the technology invented by Dr. Niwayama, associate professor, by ASTEM, Inc.
