Abstract

A method for measuring the rotational velocity of a cell is presented. In this method, a parallel pencil beam illuminates the cell and the reflected light intensity distribution from the cell surface is observed using an objective lens. In the Fourier transform plane of the lens, this light intensity distribution is translated by an amount that corresponds to the rotational velocity of the cell. This translational velocity can be converted into the rotational velocity. The authors confirmed that the rotational velocity of a cell could be measured using this method by rotating a cancer cell using light pressure.
