CCDtehnoloogiaga

CCDtehnoloogiaga refers to technology involving Charge-Coupled Devices (CCDs). CCDs are semiconductor devices that convert light into electrical charge. They are a type of image sensor that captures light and converts it into a digital signal, forming the basis for many digital cameras, scanners, and other imaging devices.

The fundamental principle of CCD technology is the ability of silicon to generate an electrical charge when exposed to photons (light particles). This charge is then moved across the sensor in a systematic way, a process called "coupling." During readout, these charges are amplified and converted into a digital value. This precise and efficient charge transfer is what gives CCDs their name.

Early digital cameras relied heavily on CCD technology. While newer technologies like CMOS sensors have become more prevalent in many consumer devices due to advantages in power consumption and manufacturing cost, CCDs still find application in areas requiring high image quality and low noise, such as scientific imaging, astronomical observatories, and high-end professional photography. The technology is known for its excellent sensitivity and uniformity.
