摘要
Optical retroreflective markers provide a strong return signal when illuminated by a source, resulting in an easy way to localize and identify an object. As current optical retroreflectors are typically bulky, we have investigated the use of the integrated silicon photonics platform to fabricate optical retroreflectors. An optical retroreflective marker with a total field of view (FOV) of about 57 degrees x 4 degrees is shown here. With a limited number of reflectors, a large FOV can then be covered.
