LBTEK solid beam steering module (Solid Beam Steering Module, SBSM) is mainly composed of liquid crystal variable retarders and liquid crystal polarization gratings. By applying different voltages output from the corresponding voltage controller, the retardation of the liquid crystal variable retarder is controlled. The incident light is modulated into left-handed or right-handed circularly polarized light after passing through the liquid crystal variable retarder. Due to the diffraction polarization-dependent characteristics of the liquid crystal polarization grating, incident light with different circular polarization states is diffracted in different directions after passing through the liquid crystal polarization grating. The cascade superposition of multiple liquid crystal variable retarders and liquid crystal polarization gratings can achieve beam deflection within a certain angular range. Compared with mechanical beam steering technology, the LBTEK non-mechanical beam steering module has the advantages of small size, fast response speed, and high stability. It also supports flexible customization of parameter specifications. For details, please consult LBTEK technical support.
