A new method for measuring the power spectrum of the quasielastic light scattering with the sinusoidal electric field (QELS-SEF) has been developed on the basis of a Wiener-Khinchin theorem extended to the periodically stationary systems such as QELS-SEF. The extended theorem enables us to obtain the power spectrum directly from the scattered light intensity without calculating the autocorrelation function.
