The experimental development of an infrared multiple-cavity electrooptically tuned Fabry-Perot filter using LiNbO(3) is described. This filter, designed for operation in the 3-5-microm spectral band, was demonstrated by angle scanning using a He-Ne laser at 3.39 microm. The multiple-cavity configuration increased the free-spectral range of the 2-A bandwidth filter from 67 to 670 A as observed in the increased angular spacing of transmission peaks. Because of the large halfwave voltage of LiNbO(3) at these wavelengths, tuning was restricted to approximately 15% of the free-spectral range.
本文描述了使用铌酸锂（LiNbO₃）进行红外多腔电光调谐法布里 - 珀罗滤波器的实验开发。该滤波器设计用于在3 - 5微米光谱波段工作，通过使用波长为3.39微米的氦氖激光进行角度扫描来演示。如传输峰角度间距增加所示，多腔配置将2埃带宽滤波器的自由光谱范围从67埃增加到670埃。由于铌酸锂在这些波长下的半波电压较大，调谐被限制在自由光谱范围的约15%。
