The world’s smallest camera is only 0.6 mm in diameter.
The smallest invisible camera is only 0.6 mm in diameter, equivalent to one-third the size of a toothpick. It can use lighting chips to take 40,000-pixel color images and capture images at a speed of 30 feet per second. However, this little thing is specially designed for medical use. Installing it in surgical tools allows doctors to see more accurate internal images during surgery and more clearly observe small lesions in the body.
In addition, the camera's low power consumption means less heat is generated, allowing for longer surgeries. This miniature camera, which is as big as sand, has entered the Guinness Book of World Records. The inventors stated: Our method paves the way for unprecedented flexibility in printing optical microdevices.
Working principle
Camera, also known as computer camera, computer eye, electronic eye, etc., is a video input device that is widely used in video conferencing, telemedicine and real-time monitoring. aspect. Ordinary people can also talk and communicate with each other with images and sounds on the Internet through cameras. In addition, people can also use it for various currently popular digital imaging, audio and video processing, etc.
The optical image generated by the lens is projected onto the surface of the image sensor, and then converted into an electrical signal. After A/D (analog-to-digital conversion) conversion, it is converted into a digital image signal and then sent to the digital signal processing chip. After processing, it is transferred to the computer through the USB interface for processing, and the image can be viewed through the monitor.
