Abstract
A widely tunable optical filter with variable bandwidth has been demonstrated based on the thermal effect on cholesteric liquid crystals. The central wavelength can be widely tuned from 826 to 517 nm and the bandwidth can be varied from 10 to 70 nm. It will have potential applications in many fields, especially in telecommunications and multi-spectral/hyper-spectral imaging systems.
摘要
基于胆甾相液晶的热效应，已展示出一种具有可变带宽的宽可调谐光学滤波器。中心波长可在826至517纳米范围内广泛调谐，带宽可在10至70纳米之间变化。它将在许多领域具有潜在应用，特别是在电信和多光谱/高光谱成像系统中。
