我们讨论利用液晶可调谐双折射滤波器。我们已经纳入了可调液晶，制造的电气可变，真正的零阶延迟器，在Lyot和Solc滤波器的设计，使连续的光谱可调谐性。讨论了几种组合可调谐滤波器的性能特点和设计改进。这些范围从用于太阳成像的窄带（0.13 nm）滤光片到用于航空遥感的宽视场滤光片，跨越400 - 2500 nm的光谱范围。讨论了液晶可调谐滤波器的视场、速度和透射率的设计考虑。
We discuss tunable birefringent filters utilizing liquid crystals. We have incorporated nematic liquid crystals, manufactured as electrically variable, true zero-order retarders, in Lyot and Solc filter designs to allow continuous spectral tunability. The performance characteristics and design enhancements of several assembled tunable filters are discussed. These range from narrow band (0.13 nm) filters for solar imaging to wide field of view filters for airborne remote sensing spanning the spectral range 400 - 2500 nm. Design considerations for improving field of view, speed, and transmission of liquid crystal tunable filters are discussed.
