Night vision device is an important optoelectronic device. It enhances, amplifies and displays targets in weak light, making it an important equipment for night observation, monitoring and combat. Night vision goggles come in a variety of modes, each with its own unique features and uses.

Thermal imaging mode:

Thermal imaging mode is an important mode of night vision devices, which uses the object's own thermal radiation to form images. This mode can work in a completely dark environment and has strong detection capabilities for targets hidden at night. Thermal imaging mode can work in various harsh weather conditions, such as fog, smoke, rain, etc., and has strong adaptability.

Infrared night vision mode:

Infrared night vision mode is another important mode of night vision devices, which uses infrared rays to observe and monitor targets. This mode can work at night and has good detection capabilities for targets in low-light environments. Infrared night vision mode can be assisted by infrared laser or infrared light source to improve observation distance and clarity.

Visible light mode:

The night vision device also has a visible light mode, which can use visible light for observation and monitoring at night or in low-light environments. This mode can provide true color images, which is of great significance for specific target recognition and monitoring. The visible light mode can work in a better light environment and plays an important role in night patrol, search and rescue.

Doppler radar mode:

The night vision device can also be equipped with a Doppler radar mode to detect the movement and speed of the target. This mode can work at night or in bad weather conditions and is important for tracking moving targets. Doppler radar mode can provide target speed, direction and distance information, which is of great significance for military operations and security monitoring.

To sum up, night vision devices have multiple modes, each with its own unique characteristics and uses, which can provide effective observation and monitoring capabilities under different environmental conditions. With the continuous development of technology, the multiple modes of night vision devices will provide more possibilities and application scenarios in fields such as night operations, security monitoring, and emergency rescue.
