Claim:
1. A multidirectional optical positioning method comprising steps of: providing a transparent board, at least one incident light penetrating the transparent board from an incident side to an emission side of the transparent board to produce multiple different radiating lights emitted from the emission side and arranged in one single axial direction of the emission side, wherein multiple different light conversion layers respectively formed of multiple different light property conversion materials are laid on a surface of the transparent board by means of polarization coating, so as to change physical properties of the incident light, the incident light is incident onto the incident side of the transparent board, and the incident light passes through the light conversion layers, whereby the multiple radiating lights with different physical effects are emitted from the emission side of the transparent board; and using a sensor positioned on the emission side of the transparent board to receive the radiating lights arranged in the single axial direction so as to find the position of the sensor according to different extents of physical effects of the different radiating lights.
