Infrared Detection Systems: Enabling Night Vision Superiority, Space Robotics, and Precision Missile Tracking

Introduction: From Scarcity to Ubiquity in Infrared Sensing Infrared (IR) detection has transitioned from a niche, high-cost capability into a foundational sensing layer across defense, space, industrial, and emerging consumer ecosystems. For decades, the field was constrained by a rigid trade-off: high sensitivity required cryogenic cooling and exotic materials, while affordability demanded compromises in performance,…
