用于下一代热成像应用的 先进红外联系变焦镜头

摘要: 在本文中我们回顾了红外变焦镜头的最新进 展,这些镜头可满足对减小尺寸、重量和功率 (SWaP) 的挑战性要求,同时能够在恶劣的环境条件 下以及在机载和便携式系统等受限平台上,实现高 的成像性能。描述了为下一代红外热成像系统和应 用优化的高级折叠式光学镜头和轻量级连续变焦镜 头的设计考量和性能。

Manufacturing High-Performance Mirrors

When it comes to long-range, multispectral optical systems, large mirrors play an integral role; there are tens of thousands of optical units containing large mirrors around the globe. With minimum diameters starting at 200 mm, the largest mirrors range from 8.2 m in diameter (single mirrors) to over 10 m (segmented). They take many shapes — spherical, aspheric, parabolic, or freeform — and are used for a wide spectrum of light, including visible, UV, and IR.
