| Experimental result. Here panels (a) and (b) show the frames without illumination, which are the first frame and the frame is about to turn on the light respectively, and their time interval is 30 s. The others show the frames with illumination. The white numbers indicate the illumination time in sec, where 0 s refers to the moment of beginning to turn on the laser beam. The black line and numbers denote the distance from the front edge of the oil drop to the right edge of the frame. The dark part in the front face of the oil drop is the shadow of the dark area of the energy-saved reading lamp. |
