  • particle image velocimetry (PIV) A whole-flow-field technique providing instantaneous velocity vector measurements in a cross-section of a flow that is seeded with micron-sized particles. CCD or CMOS cameras and laser light sheets produce real-time velocity maps by measuring the...
  • complementary metal oxide semiconductor (CMOS) An integrated circuit that uses both PMOS and NMOS devices on the same substrate, resulting in extremely low power dissipation.
  • charge-coupled device (CCD) A self-scanning semiconductor imaging device that utilizes MOS (metal-oxide semiconductor) technology, surface storage and information transfer. It consists basically of a metal insulator semiconductor (MIS) capacitor, majority carriers being...
  • fluorescence The emission of light or other electromagnetic radiation of longer wavelengths by a substance as a result of the absorption of some other radiation of shorter wavelengths, provided the emission continues only as long as the stimulus producing it is...
