This Polar Instrumentation and Technology Development (PITD) Project promises to develop several novel electro-optical instruments for atmospheric research. The goal is to produce high-luminosity, rugged and reliable instruments suitable for unattended use in polar regions. The devices will be based on the principles of Fabry-Perot interferometers which have the usual etalon gap made of an electro-optic material such as lithium niobate, which changes its effective optical thickness when an electric field is applied. The specific instruments to be developed are: a rugged, enhanced-luminosity, high resolution Fabry-Perot spectrometer; a spectrally agile filter; and a double etalon modulator. These instruments, if successfully built, should find wide application in many areas.

该极地仪器和技术开发（PITD）项目承诺开发多种用于大气研究的新型电光仪器。 目标是生产适合极地地区无人值守使用的高亮度、坚固且可靠的仪器。 这些设备将基于法布里-珀罗干涉仪的原理，该干涉仪具有由铌酸锂等电光材料制成的常用标准具间隙，当施加电场时，该标准具间隙会改变其有效光学厚度。 待开发的具体仪器有： 坚固耐用、亮度增强、高分辨率的法布里-珀罗光谱仪；光谱捷变滤波器；和双标准具调制器。 这些仪器如果成功建造，应该会在许多领域得到广泛应用。
