Topics that deal with optics as a whole, including color, ray tracing and luminescence


  • Brightness - the luminance of a body, separate from its hue or saturation
  • Color - the visual perception by humans that derives from different spectrums of light
  • Extinction coefficients - parameters that define how strongly a substance absorbs light at a given wavelength
  • Four-wave mixing - an intermodulation phenomenon in optical systems whereby interactions between two wavelengths produce two extra wavelengths in a signal
  • Luminescence - the emission of light from a substance not resulting from heat
  • Optical crosstalk - when two or more optical communication channels interfere with other each other
  • Optical design - the design of optical equipment
  • Optical distortion - the deviation from rectilinear projection in light transmission
  • Optical fiber applications - the uses of fiber optics
  • Optical harmonic generation - the process by which photons interacting with a nonlinear material are effectively combined to form new photons with twice as much energy
  • Optical losses - light which could have generated power or a signal but is dissipated or distorted
  • Optical microscopy - the use of lens to magnify and focus the image of small objects
  • Optical mixing - the process by which optical wavelengths mix and transform each other
  • Optical polarization - the polarization of certain materials upon the application of light
  • Optical pulses - short bursts of visible light
  • Optical saturation - a point at which further applications of light produce no effect
  • Ray tracing - a technique for generating an image by tracing the path of light through pixels in an image plane and simulating the effects of its encounters with virtual objects
  • Whispering gallery modes - where laser light is coupled into a circular waveguide and, with a perfect match between frequency and circumference, creates a resonance
