CCD sensor technology is usually used for high quality imaging, and it is mostly used by professionals, although there are CCD sensors available at lower prices that amateurs can buy to shoot high quality images for their personal use. The CCD sensors come in two forms, and one of them is the linear CCD sensor, while the other is the matrix sensor. The linear CCD sensor is most often used within a wide range of applications: scanners, satellite imaging, or multifunctional printers. The linear CCD sensor brings good performance and image quality, so if you are interested in purchasing such a product, this article is for you.
Linear CCD sensor composition
A linear CCD sensor is made out of photodiode arrays, consisting of active photosites for detection of RGB signals along with another channel for luminance. This combination gives top-notch images. This kind of design of photosites in a linear CCD sensor is called a quadric-linear color array design (RGB and L). Almost every linear CCD sensor has low noise design which means that it can reproduce images in a stunning high quality.
The technology behind linear CCD sensors
The linear CCD sensor works very much like the matrix CCD sensor – it converts light to digital data in a way that the light is being held on the sensor like a small electrical charge which is then processed through a register into voltage and finally into digital signals. The register of these devices is usually stronger than the register of matrix devices since the linear CCD sensor acquires much more speed and the input lag has to be minimal. The linear CCD sensor has very sensitive photodiode arrays and this delivers high quality results with little noise.
Where are they used?
The most common uses for a linear CCD sensor are in various scanning devices, multifunctional printers, satellite imaging, as well as copy machines. One more use of a linear CCD sensor is in machine vision, a process which enables automatic inspection, control of ongoing processes which are too fast for the human eye or robot guides in industry. Another field the linear CCD sensor is used in is computer vision as well, and this discipline includes navigational systems, information organization, automatic inspection, object modeling and detecting events. Every barcode scanner you use, or most hospital examinations involve some kind of a linear sensor which helps make the daily life easier in many ways. The early use of these sensors involved photocopiers and fax machines in offices, and therefore they were optimized for speed only, not so much for quality. The quality problem is mere history today, because the linear sensors have rapidly developed and they deliver the speed, but the quality too. If you want to have high quality images, we recommend that you purchase a product that has a linear sensor integrated in order to get the best quality images.
