Description
Karina Arcolezi and co-authors build a translucent mortar that transmits light while preserving privacy in a 2025 study, based on the head byline. Light transmitting building materials usually pass a coherent image, which breaks visual privacy. Their composite scatters optical fibers at random through a cement matrix inspired by a low carbon limestone clay cement, designed for sustainability and performance.
An algorithmic mapping tracks each fiber input to its output, so the scatter looks private to the eye. Yet with camera imaging and calibration, the network can be computationally reversed to recover the hidden image accurately. Tests across viewing distances and camera angles showed a stable working range with low error.
