Abstract
A theoretical and experimental study is performed to eliminate the effect of retroreflection of a camera by using masks. Theoretically, different types of masks are studied in terms of their capability to reduce the strength of the retroreflected signal while maintaining good camera image quality. Experimentally, the strength of retroreflected signals and image quality have been measured for different alignments of different masks. The results of these experiments in combination with the presented theory can be used to design masks that can reduce or even completely eliminate the strength of retroreflected signals, while simultaneously maintaining good image quality.
