What breakthroughs will there be in the detector technology of thermal imaging night vision devices in the future?

1. Materials and performance

New material research and development: Researchers will continue to explore and develop new infrared detection materials, such as two-dimensional materials such as graphene and topological insulators, and new compound semiconductor materials such as perovskites. These materials have unique physical and chemical properties, such as high carrier mobility and adjustable band gaps, and are expected to achieve higher detection sensitivity, faster response speed and wider spectral response range.

Improvements in high-performance refrigeration technology: For refrigerated detectors, new refrigeration technologies will continue to emerge to improve refrigeration efficiency, reduce refrigeration power consumption, and reduce the size and weight of refrigeration equipment. For example, micro-coolers and quantum refrigeration technologies based on micro-electromechanical systems (MEMS) will enable refrigerated thermal imaging night vision devices to achieve greater breakthroughs in performance and portability, and can be applied to more scenarios with extremely high detection sensitivity requirements.

2. Manufacturing process and integration

Improvement of high-precision manufacturing process: With the continuous advancement of semiconductor manufacturing processes, advanced processes such as extreme ultraviolet lithography (EUV) technology and atomic layer deposition (ALD) will be more widely used in the manufacture of detectors, which can achieve smaller pixel sizes, higher fill factors and more uniform detector arrays, thereby improving the resolution and imaging quality of detectors, enabling thermal imaging night vision devices to more clearly distinguish target details.

Multifunctional integration and system-level packaging: Detectors will be more highly integrated with signal processing circuits, image processing chips, etc. to form a system-level package (SiP) or system-on-chip (SoC). This integration method can not only reduce the size and weight of the detector, but also improve the reliability and performance of the system, reduce power consumption, and realize more functions, such as intelligent target recognition, automatic tracking, etc., to meet the needs of different application scenarios.

3. Detection band and resolution

Expanding the detection band: Future detector technology will continue to expand the detection band, from the currently common medium-wave infrared (MWIR) and long-wave infrared (LWIR) bands to shorter or longer bands, such as short-wave infrared (SWIR) and terahertz bands. Infrared radiation in different bands has different characteristics and application advantages. Expanding the detection band will enable thermal imaging night vision devices to better adapt to the detection needs of various complex environments and targets.

Ultra-high resolution imaging: With the continuous increase in the scale of detector arrays and the continuous improvement of manufacturing processes, the resolution of thermal imaging night vision devices will continue to improve, and it is expected to achieve ultra-high resolution imaging, such as 4K, 8K or even higher resolution. High-resolution imaging will provide clearer and more detailed target information for military reconnaissance, security monitoring, industrial detection and other fields, and improve the accuracy of target identification and analysis.

4. Intelligence and adaptability

Enhanced intelligent detection and identification capabilities: With the help of artificial intelligence and machine learning technology, detectors will have stronger intelligent detection and identification capabilities. By learning and analyzing a large amount of infrared image data, the detector can automatically identify different types of targets, classify, track and analyze their behavior, and accurately detect targets even in complex backgrounds and interference environments, reducing errors and workload of manual operations, and improving work efficiency and accuracy.

Adaptive performance optimization: Future detectors will have stronger adaptive capabilities and can automatically adjust working parameters such as detection sensitivity, integration time, spectral response range, etc. according to different environmental conditions and target characteristics. For example, under different weather conditions, different target temperature ranges and different scene backgrounds, the detector can automatically optimize performance to obtain the best imaging effect and detection performance, and improve the adaptability and reliability of thermal imaging night vision devices in complex and changing environments.
