Presentation Transcript

  1. How a CCD Works (Charge-Coupled Device) • Photons charge electrodes • Voltages from pixels is shifted off the chip • The voltage is converted to digital www.microscopy.fsu.edu/primer/digitalimaging/concepts/ccdanatomy.html

  2. How a CCD Works CCDs only register light, color is achieved using filters www.microscopy.fsu.edu/primer/digitalimaging/concepts/ccdanatomy.html
