摘要：

In this paper, a novel concept for visible light positioning is introduced, which employs a liquid crystal display as a dynamic optical filter in front of a photodetector. By electronically switching dedicated pixel areas in transparent or blocking mode, respectively, the angle of arrival is estimated. The measurement principle is supported by a mathematical model. Finally, an experimental setup is presented and measurement results are compared to the theoretical findings.
