Indigenous Development and Manufacturing of Dewar Detector Cooler Assembly (Nos of detector- 320 x 256) used in HHTI with LRF HHTI Bi-ocular
Modern thermal imaging systems depend on Dewar-based cooled infrared detectors that require reliable cryogenic cooling to deliver high sensitivity, low noise, and long-range detection. These detector coolers are mission-critical, yet they are often deployed as standalone subsystems with limited health monitoring and OEM-specific interfaces. This lack of standardised oversight can lead to undetected performance degradation, longer cooldown times, increased power draw, and unexpected failures that reduce operational readiness.
An integrated Dewar Detector Cooler management framework is needed to enable real-time monitoring of key parameters such as temperature stability, vibration, power consumption, and operating hours. The system should support predictive maintenance, fault diagnostics, and seamless integration with thermal imager electronics for safe startup and shutdown. A scalable, modular design must accommodate multiple cooler technologies and platforms while ensuring reliable operation in harsh environments. Centralised performance data would improve lifecycle management, reduce downtime, and enhance the overall reliability and availability of thermal imaging assets.
