The principle of CCD image sensor is made by using the dual functions of photoelectric conversion and charge transfer of QCD. A row of pixels are used to scan a picture, and three exposures are made to correspond to red, green and blue filters respectively. The linear sensor captures one-dimensional images.
Application of p>CCD image sensor:
1)Medical medical microscope. Using ultra-small CCD camera or optical fiber image transmission endoscope system, we can realize human microsurgery, reduce the size of surgical incision, reduce the possibility of wound infection and relieve the pain of patients. At the same time, it can also be used for real-time remote consultation and on-site teaching.
2）VehicleCamera。 Installing QCD camera in various vehicles can make drivers use CCD camera in the car, rearview mirror system in the car and display in front of the driver. Not only can you see the situation inside the car at any time, but you can also observe the road behind you when reversing, and you can also observe the distance kept by the car behind you at any time during the forward driving, which improves the driving safety.
3）Closed Circuit Television（CCTV）。 CCTV is a TV monitoring system that has been widely paid attention to by people in recent years, and it has developed into a new industry.
4）Broadcast。 It is precisely because of the development of new high-quality and high-resolution CCD camera devices that it is possible to manufacture CCD cameras suitable for radio and television, which have now developed into digital television systems.
Extended information
The structure and working principle of CCD image sensor determine that this kind of device has the following advantages:
1. CCD is a solid device with small volume, light weight, high reliability and long service life:
2. The image distortion is small and the size reproducibility is good;
3. It has high spatial resolution;
4. The geometric dimension accuracy of the photosensitive element spacing is high, and higher positioning accuracy and measurement accuracy can be obtained;
5. It has high photoelectric sensitivity and large dynamic range.
