Industry application analysis of night vision devices
1. Building outline display. Nowadays, anti-drug operations are becoming increasingly complex.
Planting has also moved from outdoors to indoors, which adds a lot of trouble to law enforcement officers in investigating and collecting evidence. The application of night vision technology solves this problem, because indoor planting requires 1 kilowatt halogen lamp lighting to provide the light and heat needed for growth. While these lamps heat the interior of the building, the heat will radiate to the outer surface of the building. This heat can be seen evaporating through the thermal imaging camera, thereby assisting the police in anti-drug operations.
2. Complete rescue missions and search for fugitives. Use low-light microscopes and thermal imaging cameras to search for missing persons or fugitives throughout the night. People are strong radiators of heat, and their location is easily determined through thermal imaging cameras. Thermal imaging cameras can also be used to spot people hiding in concealed structures. For example, when the Georgetown Police Department was escorting two criminals, their negligence caused the criminals to escape, so the police immediately began a pursuit. One of them fled to a bushy area and hid. The police passed by the hiding place of the criminal three times but could not find it with flashlights. Finally, using a handheld thermal imaging camera, the criminal was caught in just 25 seconds.
3. Ensure police safety. Using night vision technology, police officers can spot suspects at night without themselves being seen. In one case in California, law enforcement officers from the Drug Enforcement Administration used thermal imaging cameras to monitor a criminal gang suspected of secretly manufacturing drugs. This group of criminals was operating rampant in a mountain stronghold. Every night they go out to look for the police who are watching them in the woods. The police use thermal imaging cameras in the woods to prevent themselves from being discovered by the gangsters, ensuring their own safety.
4. Vehicle Tracking Vehicles emit a lot of heat both during and after use. Heat radiation comes not only from the engine, but also from tires, brakes and exhaust pipes. Police helicopters equipped with thermal imaging cameras can track suspects' vehicles from the air, even when they don't have their headlights on. Patrol cars equipped with on-board thermal imaging cameras can also track suspect vehicles that have entered the parking lot or have moved away by detecting the heat dissipation of vehicles that have just turned off.
5. It is found that the restored soil surface may not be visible with the naked eye, but it can be seen with a thermal imaging camera, because when the surface of a certain area is disturbed, the thermal profile of the surface will also be destroyed. Thermal radiation of soil that has been treated also differs from that of compacted soil. Buried things can be found with this feature of thermal imaging cameras. The police once handled a case where a man killed his wife in a rage. In order to cover up the evidence of the crime, the man buried the body in the backyard and covered the burial site with grass. The man thought he had done a perfect job, but the police The body was quickly found using a thermal imaging camera. Now, law enforcement agencies have begun using thermal imaging cameras to find where victims are buried. It is generally believed that new graves within 90 days can be found using thermal imaging cameras, but recently the American Geographical Society used thermal imaging cameras to discover an ancient Egyptian foundation 2,000 years ago.
