High-Speed Indoor Navigation System based on Visible Light and Mobile Phone
IEEE Photonics Journal, 2017 Visible light positioning (VLP) is widely believed to be a cost-effective answer to the growing demand for real-time indoor positioning. However, due to the high computational cost of image processing, most existing VLC-based systems fail to deliver ...

Visible light. Part II: Photoprotection against visible and ultraviolet light
Journal of the American Academy of Dermatology, 2021 Cutaneous photobiology studies have focused primarily on the ultraviolet portion of the solar spectrum. Visible light (VL), which comprises 50% of the electromagnetic radiation that reaches the Earth's surface and, as discussed in Part I of this CME, has cutaneous biologic effects, such as pigment darkening and erythema.

Visible‐Light Photoswitching by Azobenzazoles
Chemistry – A European Journal, 2020 AbstractThree visible‐light responsive photoswitches are reported, azobis(1‐methyl‐benzimidazole) (1), azobis(benzoxazole) (2) and azobis(benzothiazole) (3). Photostationary distributions are obtained upon irradiation with visible light comprising approximately 80 % of the thermally unstable isomer, with thermal half‐lives up to 8 min and are mostly ...
