In a recent breakthrough published in Sensor, researchers from the Changchun Institute of Optics, Fine Mechanics and Physics (CIOMP) of the Chinese Academy of Sciences have delved into the effects of high-repetition-rate CO₂ pulsed lasers on infrared imaging systems. Led by SHAO Junfeng, the team utilized sophisticated algorithms to study how such lasers can affect the target extraction and tracking performance of infrared detectors.

Infrared imaging systems are crucial for a wide range of applications, from military surveillance to environmental monitoring. However, the potential for interference from laser dazzle is a significant concern. The current study aimed to quantify the laser's dazzling effects on infrared imaging, providing valuable insights into how to mitigate potential interference.

Using the Canny edge extraction algorithm and cross-correlation template matching, the team conducted laser dazzling and damage experiments. They analyzed the normalized correlation between target and dazzling images, revealing the extent of laser interference. This analysis helped establish a quantified dazzling pattern for lasers on infrared imaging systems, an important step towards understanding and countering such interference.

The key findings indicate that high-repetition-rate CO₂ pulsed lasers can significantly impact infrared imaging, potentially interfering with target extraction and tracking. However, the study also highlights the potential for developing countermeasures, such as optimized algorithms and improved imaging technology.

The significance of this research is far-reaching. With the increasing use of infrared imaging systems, understanding how they can be affected by laser interference is crucial. The insights gained from this study can help improve the robustness of infrared imaging, ensuring more accurate and reliable results in critical applications.

In summary, the evaluation of high-repetition-rate CO₂ pulsed lasers on infrared imaging systems provides valuable insights into potential interference and countermeasures. This research marks an important step towards ensuring the continued reliability of infrared imaging in various applications.
