Positional tracking systems and methods

The virtual reality (VR) / enhanced optical positioning system in reality (AR) can be used in the application it is started. Exemplary embodiments include the one or more receivers and one or more transmitters. Exemplary transmitters includes two orthogonal rotor (rotor) that emits a fan-shaped (fan-shaped) laser beam, respectively. Each beam is swept while the rotor is rotating at a constant speed. An exemplary light receivers can be relatively small, it may be mounted at a convenient location on the VR display. These receivers are head-comprises a compact optical detector that can be mounted on the mount VR display. Exemplary systems and determines the position by measuring the time to traverse each of the receiver / detector, each of the sweep beam (swept beam).
