Abstract

The infrared conformal window is one of the most critical components in aircraft. Conformal windows with high performance bring low aberrations, high aerodynamic performance, reliability in extreme working environments, and added value for aircraft. Through the past decades, remarkable advances have been achieved in manufacturing technologies for conformal windows, where the machining accuracy approaches the nanometer level, and the surface form becomes more complex. These advances are critical to aircraft development, and these manufacturing technologies also have significant reference values for other directions of the ultra-precision machining field. In this review, the infrared materials suitable for manufacturing conformal windows are introduced and compared with insights into their performances. The remarkable advances and concrete work accomplished by researchers are reviewed. The challenges in manufacturing conformal windows that should be faced in the future are discussed.

红外保偏光学器件制造的研究现状与挑战
红外保形窗是飞机上最关键的部件之一。高性能的保形窗具有低像差、高气动性能、在极端工作环境下的可靠性,并能为飞机带来附加值。过去几十年来,保形窗制造技术取得了显著进步,加工精度接近纳米级,表面形状也变得更加复杂。这些进步对飞机的发展至关重要,同时这些制造技术也对超精密加工领域的其他方向具有重要的参考价值。本综述介绍了适用于制造保形窗的红外材料,并比较了这些材料的性能。此外,还回顾了研究人员取得的重大进展和完成的具体工作。还讨论了未来在制造保形窗方面应面临的挑战。
