The device was composed of four laminated LCCs (A0-LCC, A45-LCC, C0-LCC, and C90-LCC) compensating for Astig(0), Astig(45), Coma(0), and Coma(90), respectively. The effective optical diameter of the LCCs was 17.6 mm, which was almost equal to the calculated pupil diameter of the objective lens described later. Each LCC corrected the Zernike aberration of the Zernike coefficient within and for wavelengths of 488 nm and 900 to 910 nm, respectively, which were used for the excitations in the observations described later. The segmented transparent electrodes were formed in one of the two glass substrates in A0-LCC to generate the phase distribution required to correct Astig(0) [Figs. 1(a) and 1(b)]. Similarly, the segmented transparent electrodes for correcting Astig(45), Coma(0), and Coma(90) were formed in A45-LCC, C0-LCC, and C90-LCC, respectively [Figs. 1(c)–1(h)]. In each LCC, the segmented electrodes generated a 32-level quantized phase distribution. We applied voltages to the LCCs as required to generate the Astig(0), Astig(45), Coma(0), and Coma(90) components of the Zernike coefficients (, , , and , respectively) shown in Fig. 1(i), and the phase distribution generated in the four laminated LCCs was measured using a laser interferometer (Zygo PTI 250, Zygo Corporation). When we applied voltage to A0-LCC as required to generate an Astig(0) component of , the device showed the phase distribution of Astig(0) [Fig. 1(i)]. When we applied a voltage only to A45-LCC (), the phase distribution of the device agreed very well with that of Astig(45). Furthermore, we confirmed that the direction of the astigmatic component was rotated by applying a voltage and changing the ratio between the voltages applied to A0-LCC and A45-LCC. For example, when voltages were applied to A0-LCC and A45-LCC as required to generate a phase distribution with the same-magnitude Zernike coefficients (), the device showed the astigmatic component to be in the 22.5-deg direction. Similarly, C0-LCC of and C90-LCC of showed Coma(0) and Coma(90) phase distributions, respectively. When using C0-LCC and C90-LCC (), the device showed the coma component to be in the 45-deg direction.
