The primary objective of this research program is to play a leading role in, and provide a Canadian contribution to, the advancement of the Far-Infrared (FIR) instrumentation needed for near-term and long-term future FIR astrophysics space missions. This involves direct participation in the development of the Canadian contribution to two FIR decadal roadmap pillars: 1) cooled aperture instrumentation, and 2) interferometry. Canada has established itself as the go-to partner for low power cryogenic mechanisms and metrology, resultant from current technology developpment in cryogenic FTS technology. NASA's annual technology gap assessment currently places Canada as the leading player in cryogenic FTS, giving Canada the pole position for the next generation far-infrared space missions, which will feature FTS instrumentation. This research vision also involves exploration and advancement of spectroscopic and interferometric techniques in support of a long-term FIR spatial/spectral interferometry space mission. Finally, this involves the development and mechanical/thermal/optical/spectral characterization of space-qualified cryogenic materials and components including carbon-fibre composite materials. This research program will make contributions to many aspects along the FIR roadmap including the exploitation of current results and facilities and collaboration with future experiments, facilities, and observatories. This research will provide HQP training to many students through a combination of hands-on instrumentation development and the broad perspective provided by participation in large international collaborations. The resultant technological advances will allow astronomical observations to be undertaken in shorter observation times, over larger regions of spatial coverage, or of greater spatial resolution; all with increased sensitivity over the current state of the art. Current work in this field is at very early stages on the global field. This research program provides a ground floor opportunity to become a key partner in future-generation ground and space based FIR astronomy observatories, providing excellent opportunities to train students and researchers. While this work is in many aspects unique within Canada, and the world, it complements the existing research network both locally and internationally, and will fortify existing and anticipated international collaborations into the future.

该研究计划的主要目的是在近期和长期未来的FIR天体物理学空间任务中所需的远红外（FIR）仪器的发展中发挥领导作用，并为加拿大的贡献提供了贡献。这涉及直接参与加拿大对两个FIR decadal路线图支柱的贡献：1）冷却的孔径仪器，以及2）干涉测量法。加拿大已成为低功率低温机制和计量学的首选合作伙伴，这是由于当前的低温FTS技术发展的技术。 NASA的年度技术差距评估目前使加拿大成为低温FTS的领先球员，这使加拿大成为下一代远红外太空任务的杆位，该任务将以FTS仪器为特色。该研究视觉还涉及光谱和干涉技术的探索和进步，以支持长期的FIR空间/光谱干涉空间任务。最后，这涉及空间验证的低温材料和包括碳纤维复合材料（包括碳纤维复合材料）的开发和机械/热/光学/光谱表征。该研究计划将为FIR路线图的许多方面做出贡献，包括剥削当前的结果和设施，以及与未来的实验，设施和观测站的合作。这项研究将通过动手仪器开发以及参与大型国际合作提供的广泛观点的结合为许多学生提供HQP培训。最终的技术进步将允许在较短的观察时间，更大的空间覆盖区域或更大的空间分辨率中进行天文观察。所有这些都对目前的艺术状态提高了敏感性。该领域的当前工作已经在全球领域的早期阶段。该研究计划为成为未来生成基础和太空天文学的主要合作伙伴提供了一个一楼的机会，为培训学生和研究人员提供了极好的机会。尽管这项工作在加拿大和世界上在许多方面都是独一无二的，但它在本地和国际上都对现有的研究网络进行了补充，并将加强现有和预期的国际合作。
