%X The Brownian motion analysis is a preferable method to investigate the trapping stiffness of optical tweezers system because of its convenience and simplicity. However, there would be obvious deviation if the detector's response frequency or sampling frequency is low. Such problems are discussed and a solution is brought forward in this article.
