DM control matrix calibration. Shown are measured positions of the pinhole image from subimage 16 (out of 253) as response to the 10 Hz saw-tooth wave of voltages applied to electrodes 73, 75, and 77. The amplitude response to electrode 73 results in a movement of only ±0.06 pixels or 0″.703, but the saw-tooth wave of the image positions is well above the noise level. The numbering of the electrodes is explained in Fig. 6, and their relations to microlens 16 are indicated in Fig. 2.
