  • A liquid crystal grating(LCG) with viriable grating constants is designed to make up for the shortcomings of existing gratings, such as fixed grating constant, electrode tip discharge and the electrode edge effect, et al. As a bias is applied to different conducting regions by a control module, the local transmittance is variable and location dependent, which may achieve the transition of grating constant. In addition, the arc-shape design for honeycomb electrode can efficiently avoid the point discharge near the tip and can reduce right-angle shape effect on the deflection texture. The LCG is tested by a WGD-8A grating multi-function analyzer with a He-Ne laser as the light source. The experimental results indicate that the grating constant can be changed by the control module. With the driving voltages of 2-3.4 V, the first order diffractive intensities and their difference values of the liquid crystal grating with three different grating constants increase gradually. This type of LCG can be wildly applied in many devices, such as parallax barriers and grating rulers, which are significant for the application and development of LCGs.
