plural of S phase

A microscope that uses the change of phase when light is transmitted or reflected from a transparent or reflective specimen to form an image; used especially to study living cells.

(chemistry) A process in which the rate of a reaction in a heterogeneous two-phase system is enhanced by the addition of a substance that transfers one of the reactants across the interface between the two phases.

A form of light microscopy in which small differences in refractive index of a transparent specimen are converted into amplitude (contrast) differences in the final image.

Alternative spelling of phase-shift keying

A form of phase modulation in which digital information is transmitted through discrete changes of the phase of a carrier wave.
