Imaging sensors are devices that convert light into electrical signals, allowing us to capture images. They are commonly found in cameras, smartphones, and other optical devices. The two main types of imaging sensors are CCD (Charge-Coupled Device) and CMOS (Complementary Metal-Oxide-Semiconductor), each with its own advantages in terms of image quality, power consumption, and speed. These sensors work by detecting photons, which are particles of light, and translating them into digital data. This process enables the creation of photographs and videos, making imaging sensors essential for various applications, including medical imaging, astronomy, and surveillance.
