Physics of Image Processing Essay -- physics photo photograph digital
Missing FiguresCharacteristics of LightThere are a fewer fundamental characteristics of light that are useful to be aware of onwards proceeding with the discussion on how CCDs and Film can function to but a useful, meaningful image. One of these important fundamental qualities is the fact that indubitable light is electromagnetic radiation.Electromagnetic Radiation, Photons, and Energy LevelsElectromagnetic radiation has legion(predicate) unalike classifications. Some such classifications include AM/FM radiocommunication Waves, microwaves, visible light, x-rays, and gamma rays. A key factor in these classifications is that distributively different type or level of electromagnetic radiation contains different zippo levels. These energy levels are determined by the speed or rate that charges from a given source move to create an electric car automobile field (for instance, moving charges through an antenna or lightbulb) (Serway 1090). Hence, this oscillating electric field ha s two very important characteristics it has a frequency and a wavelength. Furthermore, light can also behave as a member in some instances. This particle of light is called a photon, and is essentially the derive of energy that a light wave has at a current frequency (the energy of a photon is not dependent on the vividness of the light, but rather only dependent upon its frequency) (Serway 1107). It is this duality of light that allows CCDs and contain to function as they do, as energy is transferred to materials through light via. photons.Since the energy of a photon is only related to its frequency, an equation (discovered by Einstein) relates photons to the electrons they produce byE = h * fWhere E is the energy of the produced electron, h is Plancks constant (6.63 * 10-34 J... ...graphic Sensitivity. 2001. 31 Mar. 2003 Gambhir.
