Abstract
An optical tracking system can include at least one scanning detector having a scanning mirror and one or more fixed photo-detectors located near the scanning mirror. The scanning mirror can be configured to deflect a light beam from a source towards a retroreflective target and the photodetectors are configured to collect a portion of the light beam that is retroreflected from the target. A scanning optical detector apparatus may optionally comprise a substrate, a scanning mirror having at least one portion monolithically integrated into the substrate, and one or more photodetectors monolithically incorporated into the substrate. It is emphasized that this abstract is provided to comply with rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the claims' scope or meaning.
