retroheijastavaan
Retroheijastavaan is a Finnish term that translates to "retroreflective" in English. It describes materials or surfaces that are capable of reflecting light back to its source with minimal scattering, regardless of the angle at which the light strikes them. This property enhances visibility in low-light conditions, making retroreflective surfaces essential for safety and signaling purposes.
The principle of retroreflection relies on special optical structures, such as microprisms, glass beads, or reflective
The development of retroreflective technology has evolved to include various forms like glass bead coatings and
Research in this field is ongoing, focusing on enhancing the optical performance, environmental resistance, and affordability
