Abstract
We have studied glasslike cholesteric liquid crystals by means of scan ning near-field optical microscopy. A periodic modulation of the optic al polarization was used in order to achieve an optical contrast due t o the birefringence of the liquid crystal. Variation of the cholesteri c pitch indicates an optical resolution of approximate to 200 nm for a wavelength of 633 nm. (C) 1998 American Institute of Physics.
