What comes to your mind when hearing about night vision? It is a pretty simple term. It means the ability to see in a low-light or even dark condition. These days, almost CCTV or security cameras are equipped with the technology. Human’s poor biological vision is the reason behind a night vision technology was created. Goggles with its technologyare the most common equipment used to see in the dark. If you want to go somewhere or watching wildlife at night, then goggles are the best pick! But, how actually these amazing kits turn darkness into brightness?
How does it work?
There are two different ways of how this technology works, namely thermal Imaging and Image intensification.
It needs to capture the higher section of the light spectrum that is released as heat energy by objects rather than being reflected as light. By this capture, the temperature is easily detected. You may not be able to see in the dark, but you can feel the heat with high intensity. However, there are some disadvantages found with thermal imaging such as poor quality image, too expensive, and you can’t see the targeted objects if there are see-through obstacles in your field of view.
The image intensification method involves the implications of ambient light. It detects the low-level of light and after that magnifies it. When a tiny energy packet that makes up the light (photon) comes into an enhancer of an image, it will strike a layer called a photocathode to discharge electrons. Those electrons then will hit the second layer (microchannel plate) which increases the electrons before hitting the phosphor screen. Afterward, it will be converted back to produce light. Now there are many more electrons you will get for a brighter reflection. However, this method will fail if there is no sufficient beam for the thermal enhancer to notice by any means.
The technology was initially created for warfare. The military generally uses three major kits of night vision technology such as weapon scopes, goggles, and hand-held sighting scopes. Nowadays, the application of this technology is not only for the military but also for security. An NVD (night vision device) is lately also used by civilians such as EVS (enhanced vision system) which is used by aircraft to enhance the situational responsiveness of pilots to avoid accidents.
Another popular application is NVG (night vision goggles) a device with double eyepieces. It is combined with magnification lenses to forms binoculars. It can also be used in vehicles. A system called automotive night vision is utilized to improve the perception of a driver as well as seeing distance in poor weather or darkness. It typically uses infrared cameras which combined with the technique of active illumination to collect information to be displayed to the vehicle’s driver. The system is currently available in premium types of vehicles.
In a brief, the technology of night vision has many uses such as for law enforcement and military. Furthermore, it is also helpful for surveillance and navigation.
You often send message via email and the reply is much formal with the standard content. Company has system that will answer and reply all similar questions with automatic message. This is the foundation of chatbot. Unlike email, you communicate directly via application or online. The term refers to app, system, platform, and software that generate human-like conversation. The most sophisticated chatbot utilizes artificial intelligence that mimics human behavior, response, and attribute. You think the answer is from a real person.
Implementations of Chatbots
In general, this kind of technology has been around since the invention of telephone. In that time, companies received order and complaints from clients. After collecting data, they saw some repetitive questions and orders. To avoid answering the same question more often, an automatic system was developer. The next list shows some implementations you often find with chatbot.
The most common use of this technology is messaging app. Some developers create this app with automatic answering for several questions. Some popular apps have features to automate reply. On the other hand, you also see some software that generates human conversation.
The advanced implementation is virtual assistant. This one emerged when internet and communication integrated into human life. The simple example is music app that receive task from the owner and deliver it. You just say the word and the assistant will answer. The most sophisticated version is the assistant can handle complex tasks even project.
The practical use of chatbot is customer service. Company can reduces employees who handle complaints. Some calls have same content, which mean they will have the same response. On the other side, customer service still considers human attributes. When receiving answers, the content or message will look as if it comes from the real person.
The next implementation is in education field. More people use smartphone that can access internet with tons of app. This situation also changes the way of learning. You should install apps with valuable knowledge. To deliver the best learning experience, the app utilizes chatbot. It is useful when users cannot see or read at the moment. They rely on listening.
The next implementation is artificial intelligent. Automatic response and virtual assistant are the early adoption of AI. Even though they do not use complex algorithm, the purpose is relatively similar. Today, chatbot is added into AI system to do more than answer and help. It can analyze, decide, act, and do as human.
One thing you cannot forget is this technology becomes much entertaining to relax and enjoy. You see some entertainment, party, and anything for dun utilize chatbot. In general, this implementation depends on previous development. When virtual assistant and AI become more advanced, you also see the adoption in the entertainment industry.
