Abstract :
The amplitude modulation of the optical transmission through a cholesteric-nematic phase-change film is explained in terms of the oscillation of the helical structure discussed by Parsons and Hayes. This behaviour is seen with both tone-burst and e.w. excitation, and may be important in displays based on the fast-phase-change erect.
