Application Note: IR Zoom Lenses for Long-Range Security and Surveillance Applications

BACKGROUND In the security and surveillance markets, long range, infrared (IR) imaging plays an increasingly important role for monitoring, tracking, and targeting. The worldwide market for IR systems for commercial and dual-use security and surveillance applications is estimated to grow rapidly and reach a total of $243 million dollars by 2025,[1] with a CAGR of 6.1% (2019-2025).

The observation-systems industry has significantly evolved and grown in recent years. Alongside this growth, we have seen the development of security and surveillance imaging applications with increasingly advanced infrared imaging systems, containing detectors that are larger in size and smaller in pixel size, which present challenges for thermal imaging optical systems. These include low SWaP, lightweight requirements, while maximizing imaging performance in line with detector capabilities, allowing for high resolution vision.

次世代サーマルイメージングアプリケーション向けの高度なIRズームレンズ

Abstract: We review recent advances in the development of infrared zoom lenses that meet challenging requirements for reduced Size, Weight, and Power (SWaP) while enabling high resolution vision and identification in harsh environmental conditions and constrained platforms such as airborne and portable systems. The design considerations and performance of advanced folded-optics and lightweight zoom lenses optimized for next generation infrared thermal imaging systems and applications are described.

概要:視界不良、特に夜間や霧、煙、豪雨、雪などの悪天候下の視界不良は、世界的に交通事故の主な原因になっています¹。ナイトビジョンシステムは、特にこのような困難な状況下で、車両や歩行者の安全性を高めるためにしばしば使用されています。このようなシステムの光学系開発には、衝突のリスクを最小限に抑え、最大の性能を発揮するために、高画質の赤外線画像と遠距離の物体検出機能が求められます。

ウェビナー–ドローン用のIRオプティクス:最小限が重要

While drones are relatively new additions to the military’s stable of high-tech robotic systems, ground-based robots have been in use for more than a decade. From detecting, defusing, and disposing of explosives to working side-by-side with soldiers in the field, robots have found a myriad of applications within the military. In this webinar we’ll present products case-studies for the drone and UAV commercial and defense markets. The webinar highlights how robotic systems – both airborne and ground-based – are easing the risks and burdens faced by modern warfighters.

高性能ミラーの製造

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.

アプリケーションノート:ドローンの光学ニーズに応える

最近のUAVシステム開発では、UAV業界の光学的ニーズが注目されています。ディテクターが大型化しピクセルサイズが小さくなるにつれて、より高いMTF値とより低いF値を備えたUAV光学系が、撮像性能を最大化する鍵になります。
