This paper proposes an effective approach to fabricate a blue phase liquid crystal (BPLC) microlens array based on a photoconductive film. Owing to the characteristics of photo-induced conducting polymer polyvinylcarbazole (PVK), in which conductivity depends on the irradiation of UV light, a progressive mask resulting in the variation of conductivity is adopted to produce the gradient distribution of the electric field. The reorientations of liquid crystals according to the gradient distribution of the electric field induce the variation of the refractive index. Thus, the incident light experiences the gradient distribution of the refractive index and results in the focusing phenomenon. The study investigates the dependence of lens performance on UV exposure time, the focal length of the lens, and focusing intensities with various incident polarizations. The BPLC microlens array exhibits advantages such as electrically tunability, polarization independence, and fast response time.

Wavefront Correction

Wavefront correction plays significant role in some fields like astronomical observation, laser processing and medical imaging, etc. Liquid crystal spatial light modulator ( LC SLM) is an ideal device for high-resolution wavefront correction because of its low cost, low consumption, large number of pixels and independent programming control of each unit. It is researched experimentally that LC SLM is used as a wavefront correction device and corrects arbitrary wavefront aberration. Wavefront correction is performed based on phase conjugation and periodic phase modulation with modulo-2π. The experimental results show that the PV value of the irregular wavefront aberration is 1.56λ, RMS value is 0.25 and Strehl ratio is 0.08 before correction, but the PV value of the residual aberration is reduced to 0.26λ, RMS value is 0.02 and Strehl ratio is increased to 0.97 which is approximated diffraction limit after correction. It is proved to be feasible and effective that LC SLM is used to the high-precision and high-resolution wavefront correction.
