厚い液晶ゲル膜に電気的に誘起される巨大位相勾配を利用した高速ノンメカニカルビームステアリング

Non-mechanical beam steering (NMBS) based on liquid crystals (LCs) is of massive interest in recent years for potential applications such as autonomous vehicles and near-eye displays. To date, most of the studies associated with NMBS based on LCs employ optical phased array (OPA), which utilizes principle of optical diffraction. However, LC-based NMBS have a drawback in that the steering speed is very slow. In this study, we demonstrate refraction-type non-mechanical beam steering with high steering frequency of more than 1 kHz by using a thick LC gel films.
