METHOD AND SYSTEM FOR DETERMINING A RELATIVE POSITION TO A TARGET

摘要

A method for determining the relative angular direction θ between a target and a transmitter. A generation of one or more light beams at the transmitter comprises diffracting broadband light in such a way that different optical frequency wavelengths are diffracted differently and a relative angular direction θ is detected by reading the optical frequency wavelength. A system is provided for determining the relative angular direction between a target and a transmitter and a system is provided for determining a relative position between a target and a transmitter in an area, wherein relative position is defined by the parameters: relative angular direction (θ1, θ2), and distance.

1. A method for determining the relative angular direction θ between a target and a transmitter, the method comprising the following steps:
producing one or more light beams, transmitting, by the transmitter, such one or more light beams, wherein a light beam indicates a relative angular direction from the transmitter, receiving, by the target, one or more of the light beams, wherein the generation of the one or more light beams comprises diffracting broadband light in such a way that different optical frequency wavelengths are diffracted differently and a relative angular direction θ is detected by reading the optical frequency wavelength.
