Abstract

In applications of high power hand lasers, as addition to the standard eyes protection, it is suggested to use protective garment to avoid skin burns. Fabrics used for this kind of garment have to pass respective qualification tests. One of test procedures is optical characterization of the fabric - measurement of its reflectance, transmittance and angular characteristics of reflection of laser radiation. In this article a method for simplified measurement of these features is presented, which uses light reflection models called BRDF (Bidirectional Reflection Distribution Function) and function fitting with numerical optimization. It allows for quantitative estimation of mentioned optical properties with lower effort and shorter time than with classical methods.
