Title: TRANSPORTATION VEHICLE AND LIGHT-BEAM CONTROL DEVICE AND LIGHT-BEAM CONTROL METHOD THEREOF
Abstract:
Provided is a light-beam control device (10) of a transportation vehicle, comprising a distance measurement device (3) and at least one controllable polarizer (2). The distance measurement device (3) measures the distance between a first transportation vehicle (11) on which said distance measurement device (3) is located and an interference light source. The at least one controllable polarizer (2) is configured to perform polarization processing on a light beam if said distance is within a preset range, causing the intensity of the light beam to weaken; otherwise, polarization processing on the light beam is ceased.
