Paper Abstract

The development and use of an automatic system to measure the absolute retroreflectance of various surfaces without any reference standard is described in this paper. Preliminary results are obtained for several samples: defused SiC plates coated with gold, unworked aluminum sprayed with different thickness of paint and metal plate sprayed with different SiN powder and paint mixtures. The results indicate that a correct choice of the parameters allows complementary information of the retroreflection. The accuracy of the system is confirmed to be from 1% to 9% of measured value (for a CO2 laser source), and higher accuracy may be obtained for other wavelength.
