time， this paper uses Fourier transform to process square-wave modulated optical signals to reduce the response
time，and optimizes the reflection effect of optical signals in the transmission process， then establishes a positioning
system model with high accuracy and fast response time.Based on the function describing the relation of light
intensity and distance， the correction of the incline plane has been founded which helps to solve the coordinates of
the receiver.By applying the theory to the positioning device， the visible light positioning system with fast response
and high precision is finally realized.
