摘　　要：F- P型可调谐液晶光学滤波器是一种小体积窄带宽低压调谐滤波器。液晶作为腔内工作物质,其损耗对器件的性能有重要的影响。文章以F- P干涉仪为基础,分析了液晶损耗对这类滤波器的半强度带宽(FWHM) 和峰值透过率的影响,以利于不同要求的滤波器的设计制作。The F-P type tunable liquid crystal (LC) optical filter is a kind of compact tunable filter with narrow bandwidth and low tuning voltage. The loss of LC, which is used as work substance in the cavity, has great effects on the characteristics of this device. The influence of the loss of LC on the peak transmissivity and bandwidth (FWHM) of the device is emphatically analyzed based on F-P interferometer,so that different kinds of filters can be designd.
