Optical tracking using charge-coupled devices
WebA charge-coupled device (CCD) is an integrated circuit containing an array of linked, or coupled, capacitors.Under the control of an external circuit, each capacitor can transfer its electric charge to a neighboring capacitor. CCD sensors are a major technology used in digital imaging.. In a CCD image sensor, pixels are represented by p-doped … WebCharge-Coupled Devices and Solid State Optical Sensors III Editor (s): Morley M.
