Today, there are different types of autonomous robots. Some of them have had a major impact on our lives, such as industrial and medical robots. Others are for military use, such as drones and pet robots just for fun. The key difference between such robots and controlled robots is their ability t...
The lens chief ray angle is the angle between the optical axis and the lens chief ray. The lens chief ray is the ray that passes through the aperture stop of the optical system and the line between the entrance pupil’s center and the object point. The reason for the existence of CRA in the ...
The development and application of optics has helped modern medicine and life sciences enter a stage of rapid development, such as minimally invasive surgery, laser therapy, disease diagnosis, biological research, DNA analysis, etc.

Today, with the popularity of AI, more and more innovative applications need to be assisted by machine vision, and the premise of using AI to “understand” is that the equipment must be able to see and see clearly. In this process, the optical lens The importance is self-evident, among...
Biometrics are body measurements and calculations related to human characteristics. Biometric authentication (or realistic authentication) is used in computer science as a form of identification and access control. It is also used to identify individuals in groups that are under surveillance.

1. What is a time-of-flight (ToF) sensor?
What is a time-of-flight camera? Is it the camera that captures the flight of the plane? Does it have something to do with planes or planes? Well, it’s actually a long way off!
ToF is a measure of the time it takes for an object, particle or wave to...
Types of industrial lens mount
There are mainly four types of interface, namely F-mount, C-mount, CS-mount and M12 mount. The F-mount is a general-purpose interface, and is generally suitable for lenses with a focal length longer than 25mm. When the focal length of the objective lens is less than...
With the improvement of people’s safety awareness, home security has risen rapidly in smart homes and has become an important cornerstone of home intelligence. So, what is the current status of security development in smart homes? How will home security become the “protector” of...
1. What is an action camera?
An action camera is a camera that is used to shoot in sports scenes.
This type of camera generally has natural anti-shake function, which can capture pictures in complex motion environment and present clear and stable video effect.
Such as our common hiking, cycling, ...
A fisheye lens is an extreme wide-angle lens, also known as a panoramic lens. It is generally considered that a lens with a focal length of 16mm or a shorter focal length is a fisheye lens, but in engineering, a lens with a viewing angle range of more than 140 degrees is collectively called a fis...
