论文摘要
我们已经开发了一套新型的红外阻滞过滤器，该过滤器是通过将散射颗粒嵌入聚合物气凝胶底物中的。我们的发展使我们可以根据基本气凝胶材料的组成和散射颗粒的特性来调整过滤器的光谱性能。从地面CMB实验到行星科学探针，我们的过滤器针对多种应用。我们总结了迄今为止已经制造和测试的制剂，包括几种含有钻石散射颗粒的大小分布的多酰亚胺基碱式气囊制剂。我们还描述了用于测量过滤器光学特性的光谱表征技术，包括开发MM波傅立叶变换光谱仪测试台。
We have developed a suite of novel infrared-blocking filters made by embedding scattering particles in a polymer aerogel substrate. Our developments allow us to tune the spectral performance of the filters based on both the composition of the base aerogel material and the properties of the scattering particles. Our filters are targeted for use in a variety of applications, from ground-based CMB experiments to planetary science probes. We summarize the formulations we have fabricated and tested to date, including several polyimide base aerogel formulations incorporating a range of size distributions of diamond scattering particles. We also describe the spectral characterization techniques used to measure the filters' optical properties, including the development of a mm-wave Fourier transform spectrometer testbed.
