这项小型企业技术转移（STTR）第一阶段研究项目提出了一种新的液晶制造方法，用于带宽可控的自适应传输可调谐光带通滤波器。它动态地将可变的窄带光谱成分从可见光传递到红外（IR）。该滤波器的性能特点，特别是可变带宽，是目前的商业产品和最先进的技术无法实现的。该滤波器是许多光子仪器的重要支持组件，如多光谱和高光谱成像系统，地雷探测器，以及用于自由空间光通信的跟踪，测距和测量的光束转向。该计划的成功将导致可调谐带通滤波器的新制造方法。它将提供革命性的液晶滤波器制造方法，以制造具有高效率、低损耗、快速调谐速度和低调谐电压的高品质液晶的可变带宽可调谐带通滤波器。可调谐滤波器本身将产生强大的新仪器。

This Small Business Technology Transfer (STTR) Phase I research project proposes a novel liquid crystal manufacture approach for an Adaptive Transmissive Tunable Optical Band-Pass Filter with Controllable Bandwidth. It dynamically passes a variable narrow band spectral component from the visible to the infrared (IR). The filter's performance characteristics, particularly the variable bandwidth, are not attainable with current commercial products and state-of-the-art technologies. This filter is a vital enabling component for many photonics instruments such as multi- and hyper-spectral imaging system, mine detector, and optical beam steering for tracking, ranging and measuring for free-space optical communication.The success of the program will lead to novel manufacture approach(s) for tunable band-pass filters. It will provide revolutionary liquid crystal filter manufacturing approaches to fabricating tunable band-pass filters with variable bandwidth with high figure-of-merit liquid crystals with high efficiency, low loss, fast tuning speed, and low tuning voltage. The tunable filter itself will lead to powerful new instruments.
