Paper Abstract

Optical methods of detection of ferroelectric modes are described in detail and compared with the dielectric method. The advantages of both methods are discussed. It is concluded that the dielectric method is simple whereas the optical method is more sensitive. The optical response is free of the background steaming from nonferroelectric polarization mechanisms which are always present in the dielectric reponse. The realxation of the Goldstone- and soft modes in a room temperature ferroelectric liquid crystal has been investigated using dielectric and optical methods. Both methods have given concordant results.
