Influence of illuminance on indication detectability during visual testing

open access: yes, 2022
Visually detecting irregularities on components is a complex process, influenced by physical, technical, and human factors. Current standards mainly focus on illuminance, demanding highest accuracy for it, without providing scientific justification.

Effect of Interior Chromaticness on Space Brightness

open access: yesi-Perception, 2011
To design a lighting environment, horizontal illuminance is generally used as the brightness of a room. But it is reported that a subjective brightness does not always match the horizontal illuminance.

Ambient light level varies with different locations and environmental conditions: Potential to impact myopia.

open access: yesPLoS ONE, 2021
PurposeConsidering that time spent outdoors is protective for myopia, we investigated how ambient light levels reaching the eye varies across 9 outdoor and 4 indoor locations in 5 different environmental conditions.MethodsIlluminance (lux) was recorded ...

Dual‐Mode Electrophoretic Displays Enabled by Quantum Dot‐Decorated PR48:2 Pigment Particles and TiO2 for All‐Weather Visibility, Excellent Bistability, and Enhanced Readability

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study presents a novel quantum dot electrophoretic display (QDEPD), which combines electro‐controlled reflection and optically‐triggered emission to achieve efficient multi‐modal switching within a single pixel. By incorporating multi‐component nanostructures, the system enhances functional integration and multi‐modal response capabilities.

Evaluation of illuminance convergence in the intelligent lighting system : based on the measured illuminance distribution [PDF]

open access: yes, 2012
オフィスにおける照度評価に関する研究は広く行われている.しかし,多数の照度センサを用いた計測は困難であることから,現在までオフィスにおける照度の分布が実測された例はほとんど無い.そこで,我々は160台以上の照度センサから得られた照度データをリアルタイムに照度分布として可視化するシステムを構築した.一方,我々は,ワーカの執務内容や好みにより異なる照度を提供することができる知的照明システムを提案した.知的照明システムでは,各ワーカに異なる照度を提供するため照度分布の評価は重要である.そこで本研究では ...

Bio‐inspired artificial retina with receptive fields for in‐sensor multiply‐and‐accumulate operations

open access: yesInfoMat, EarlyView.
We developed a bio‐inspired artificial retina in which curved artificial receptive fields composed of perovskite photoconductors perform multiply‐and‐accumulate operations through in‐sensor computing. This architecture simultaneously realized the structural efficiency of human eyes (compact single‐lens imaging system) and functional advantages of ...
