Progress in Infrared Transparencies under Opto Electro Thermo and Mechanical Environment

【Abstract】

In recent years, there has been a growing interest and research focus on infrared optical thin films as essential components in infrared optical systems. In practical applications, extreme environmental factors such as aerodynamic heating and mechanical stresses, electromagnetic interferences, laser interferences, sand erosions, and rain erosions all lead to issues including cracking, wrinkling, and delamination of infrared thin films. Extreme application environment imposes stringent requirements on functional films, necessitating high surface hardness, stability, and adhesion. Additionally, for multispectral optical transmissions, infrared optical thin films are expected to exhibit high transmittance in the visible and far-infrared wavelength bands while possessing tunability and optical anti-reflection properties in specific wavelength ranges. Electromagnetic shielding requires superior electrical performance, while resisting laser interference demands rapid phase change capabilities. This talk focuses on current research progresses in infrared optical thin films under extreme conditions such as opto, electro, thermo and mechanical environments Future opportunities and challenges are also highlighted.

近年来,作为红外光学系统中的重要组成部分，红外光学薄膜的研究越来越多。在实际应用场景中，诸如气动热/力、电磁干扰、激光干扰、砂蚀雨蚀等极端环境都会导致红外薄膜出现裂纹、皱褶和脱落等问题。极端的应用环境对功能性薄膜提出了严苛要求，需要薄膜具有高表面硬度、稳定性和附着力。此外，对于多光谱光学透过来说，红外光学薄膜需要在可见光甚至到远红外波段具有高透过率，同时在特定波长范围内具有可调谐性和光学减反射特性。电磁屏蔽要求薄膜同时具有优越的电性能，而抗激光干扰则需要具有快速的相变能力。本演讲重点介绍了在光、电、热和机械环境等极端条件下红外光学薄膜的研究进展，同时也突出了未来的机遇和挑战。
