ToF (Time of Flight) lenses are lenses manufactured based on ToF technology and are used in many fields. Today we will learn what the ToF lens does and what fields it is used in.

1.What does a ToF lens do?

The functions of the ToF lens mainly include the following aspects:

Distance measurement

ToF lenses can calculate the distance between an object and the lens by firing a laser or infrared beam and measuring the time it takes for them to return. Therefore, ToF lenses have also become an ideal choice for people to carry out 3D scanning, tracking and positioning.

Intelligent Recognition

ToF lenses can be used in smart homes, robots, driverless cars and other fields to identify and judge the distance, shape and movement path of various objects in the environment. Therefore, applications such as obstacle avoidance of driverless cars, robot navigation, and smart home automation can be realized.

Attitude detection

Through the combination of multiple ToF lenses, three-dimensional attitude detection and precise positioning can be achieved. By comparing the data returned by the two ToF lenses, the system can calculate the angle, orientation and position of the device in three-dimensional space. This is the important role of ToF lenses.

2.What are the application areas of ToF lenses?

ToF lenses are widely used in many fields. Here are some common application fields:

3D imaging field

ToF lenses are widely used in the field of 3D imaging, mainly used in 3D modeling, human posture recognition, behavior analysis, etc. For example: In the gaming and VR industries, ToF lenses can be used to break game blocks, create virtual environments, augmented reality and mixed reality. In addition, in the medical field, the 3D imaging technology of ToF lenses can also be used for imaging and diagnosis of medical images.

3D imaging lenses based on ToF technology can achieve spatial measurement of various objects through the time-of-flight principle, and can accurately determine the distance, size, shape, and position of objects. Compared with traditional 2D images, this 3D image has a more realistic, intuitive and clearer effect.

The application of ToF lens

Industrial field

ToF lenses are now increasingly used in industrial fields. It can be used in industrial measurement, intelligent positioning, three-dimensional recognition, human-computer interaction and other applications.

For example: In the field of robotics, ToF lenses can provide robots with more intelligent spatial perception and depth perception capabilities, allowing robots to better complete various operations and achieve precise operations and rapid response. For example: in intelligent transportation, ToF technology can be used for real-time traffic monitoring, pedestrian identification and vehicle counting, and can be applied to smart city construction and traffic management. For example: in terms of tracking and measurement, ToF lenses can be used to track the position and speed of objects, and can measure length and distance. This can be widely used in scenarios such as automated item picking.

In addition, ToF lenses can also be used in large-scale equipment manufacturing, aerospace, underwater exploration and other industries to provide strong support for high-precision positioning and measurement in these fields.

Security monitoring field

ToF lens is also widely used in the field of security monitoring. ToF lens has a high-precision ranging function, can achieve the detection and tracking of space targets, suitable for a variety of scene monitoring, such as night vision, hiding and other environments, ToF technology can help people through the reflection of strong light and subtle information to achieve monitoring, alarm and identification and other functions.

In addition, in the field of automotive safety, ToF lenses can also be used to determine the distance between pedestrians or other traffic objects and cars in real time, providing drivers with important safe driving information.

3.Application of ChuangAn ToF lens

After years of market accumulation, ChuangAn Optics has successfully developed a number of ToF lenses with mature applications, which are mainly used in depth measurement, skeleton recognition, motion capture, autonomous driving and other scenarios. In addition to existing products, new products can also be customized and developed according to customer needs.
