Abstract

The purpose of high visibility products is to reflect light at a low angle towards the source, such as vehicle headlights. The article presents measurements of the photometric properties of selected retroreflective materials made either of microlenses on a textile base or microprisms on a polymer base. The effects of the structure of the textile and polymer layers on the photometric properties of high visibility materials is analysed and the test methods applied are described.
