An optical identification (ID) system has been built, and dynamic ID tags are compared, which include a home-made tunable cat's eye retroreflector array, a liquid crystal (LC) spatial light modulator (SLM) combined with a retroreflective tape, a LC S

This study has developed an independently-addressed tunable cat's eye retroreflector array for an optical identification system. Switchable cat's eye retroreflectors are achieved by incorporating polymer dispersed liquid crystal film and indium tin o

We have built an optical identification system, and tried different types of dynamic ID tags, including a tunable cat's eye retroreflector array, a liquid crystal (LC) spatial light modulator (SPM) with retroreflective tape, and a LC SPM with normal

In this paper, a module of a tunable micro cat's eye retro-reflector array is used as an optical identification (ID) tag. Dynamic images are generated and the module exhibits a limited viewing angle as desired. This brings a more secure identificatio
