  "textContent": "A method, apparatus and system for performing optical positioning. The apparatus comprises a laser transmitter configured to transmit a laser beam toward a retroreflector, where the location of retroreflector is known and the retroreflector reflects the laser beam and imparts modulation onto the laser beam. An optical receiver receives the reflected laser beam reflected from the retroreflector and a processor extracts a code from the modulation, determines the location of the retroreflector and calculates the distance from the apparatus to the retroreflector and uses the code and distance to determine a position of the apparatus.",
