The working principle and application fields of infrared night vision devices

Infrared night vision device is a device that uses infrared technology and photoelectric conversion technology to observe targets in dark environments. It can convert infrared radiation that cannot be perceived by the human eye into images that can be seen by the human eye, and can provide High-quality images and videos are important technical equipment and are widely used.

1. Working principle of infrared night vision device

Infrared night vision devices can observe targets and obtain image information in complete darkness or very weak ambient light conditions. Its working principle is to use the infrared radiation emitted or reflected by the object itself to detect targets in low light, no light or night conditions. The target is illuminated, and at the same time it senses and receives the infrared radiation information generated by the illuminated object, and then amplifies the signal and then displays it on the display screen to facilitate human observation.

2. Application areas of infrared night vision devices

The main function of infrared night vision devices is to expand the detection capabilities of objects outside the visible spectrum range of the human eye, and to achieve target detection and monitoring tasks at night and in low-light environments. It is mainly used in the following fields:

(1) Military and security fields

Infrared night vision devices can conduct reconnaissance, surveillance or search of targets at night or in harsh weather, improving the effectiveness of military operations. At the same time, it is also widely used in public security, firefighting, security and other fields to enhance the effect of night patrol, investigation and rescue.

(2) Industrial field

In industrial production, it is often necessary to inspect and maintain equipment or products in low light or dark environments. Therefore, infrared night vision devices are also used in industrial fields such as robots, drones, mining, and oil drilling.

(3) Medical field

Hospitals, ambulances and other units need to perform first aid and surgery operations at night. The use of infrared night vision devices in these scenarios allows doctors to clearly see and diagnose the patient's condition.

(4) Entertainment field

Infrared night vision devices are also used in some entertainment activities due to their unique visual effects, such as night sightseeing, adventure activities, hunting, etc.

The optical lens system is an important part of the infrared night vision device, including objective lens, prism, pedestal, etc., which is used to collect light from surrounding targets and convert it into electronic signals. Innova Optics has independently developed a variety of objective lenses and eyepieces that can be used in infrared night vision devices.
