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标是在近期和长期未来 FIR 天体物理太空任务所需的远红外 (FIR) 仪器的发展中发挥主导作用，并为加拿大做出贡献。这涉及直接参与加拿大对远红外十年路线图两大支柱的贡献：1) 冷却孔径仪器，2) 干涉测量。由于低温 FTS 技术当前的技术发展，加拿大已成为低功率低温机制和计量学的首选合作伙伴。 NASA 的年度技术差距评估目前将加拿大列为低温 FTS 领域的领先者，使加拿大在下一代远红外太空任务中处于领先地位，该任务将采用 FTS 仪器。该研究愿景还涉及光谱和干涉测量技术的探索和进步，以支持长期 FIR 空间/光谱干涉测量太空任务。最后，这涉及航天级低温材料和组件（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，包括利用当前成果和设施以及与未来实验、设施和天文台的合作。这项研究将通过仪器开发实践和参与大型国际合作提供的广阔视野相结合，为许多学生提供 HQP 培训。由此产生的技术进步将使天文观测能够在更短的观测时间内、在更大的空间覆盖区域或更高的空间分辨率下进行；与当前技术水平相比，所有这些都具有更高的灵敏度。目前该领域的工作在全球范围内还处于非常早期的阶段。该研究项目提供了成为未来一代地面和太空远红外天文观测站关键合作伙伴的底层机会，为培训学生和研究人员提供了绝佳的机会。虽然这项工作在许多方面在加拿大乃至世界上都是独一无二的，但它补充了本地和国际上现有的研究网络，并将加强现有和预期的未来国际合作。
