To rotating single cells, we harness light pressure generated by light absorption as a rotating torque, illuminating the two proximal points from different directions using two beams. Rotational speed is controlled by optical pulse width modulation (PWM) that controls the amount of light received per unit of time by controlling the time of illumination. To change the illumination time, the pencil of rays is scanned by a galvanometric mirror.
