The Spectrum of Light Emitted by LED Using a CMOS Sensor-Based Digital Camera and Its Application

open access: yesSensors, 2022
We introduced a digital photo image analysis in color space to estimate the spectrum of fluor components dissolved in a liquid scintillator sample through the hue and wavelength relationship.

Image Reconstruction and Investigation of Factors Affecting the Hue and Wavelength Relation Using Different Interpolation Algorithms with Raw Data from a CMOS Sensor

open access: yesPhotonics, 2023
An image processing method was employed to obtain wavelength information using light irradiated during camera exposure. Physically, hue (H) and wavelength (W) are closely related. Once the H value is known through image pixel analysis, the wavelength can

Feasibility Study on the Discrimination of Fluor Concentration in the Liquid Scintillator Using PMT Waveform and Short-Pass Filter

open access: yesSensors, 2023
Neutrinos are difficult to detect because they weakly interact with matter, making their properties least known. The response of the neutrino detector depends on the optical properties of the liquid scintillator (LS).

The Search for Double Beta Decay With Germanium Detectors: Past, Present, and Future

open access: yesFrontiers in Physics, 2019
High Purity Germanium Detectors have excellent energy resolution; the best among the technologies used in double beta decay. Since neutrino-less double beta decay hinges on the search for a rare peak upon a background continuum, this strength has enabled

Constraints on a generalization of geometric quantum mechanics from neutrino and B 0- B 0 ¯ $$ \overline{B^0} $$ oscillations

open access: yesJournal of High Energy Physics
Nambu Quantum Mechanics, proposed in Phys. Lett. B536, 305 (2002), is a deformation of canonical Quantum Mechanics in which the manifold over which the “phase” of an energy eigenstate time evolves is modified.
