| Summary: | 碩士 === 國立交通大學 === 光電工程研究所 === 106 === LC lens have the advantages of active tuning, light weight, and small component. It has potential to replace the traditional lens modules. This thesis is focused on the simple design and fabrication of liquid crystal lens to achieve the largest beam deflec-tion angle. The printed thin PEDOT:PSS line by aerosol jet printing system was ap-plied as a voltage control line on the electrodes. The continuously decay of gradient voltage was found in PEDOT:PSS line when voltage applied. As a result, the yielding gradient of the refractive index distribution was obtained. The direction and deflection angle of the output light were followed the applied voltage. In short, the 150 m PEDOT:PSS line with the resistivity ~5.55 ×10-3 Ω˙m had the best voltage distribution. The modulation voltage was 5 V, 1 kHz for the 28 m cell. The deflection angle can achieve 3.6˚, 8.0˚, and 11.6˚ at the wavelength of 633, 532, and 405 nm, respectively.
