High speed adaptive liquid microlens array.
Liquid microlenses are attractive for adaptive optics because they offer the potential for both high speed actuation and parallelization into large arrays. Yet, in conventional designs, resonances of the liquid and the complexity of driving mechanisms and/or the device architecture have hampered a successful integration of both aspects. Here we present an array of up to 100 microlenses with syn...
متن کاملSwitchable 2D/3D Display – Solid Phase Liquid Crystal Microlens Array
A new solid phase liquid crystal microlens array has been applied to Polarisation Activated Microlens flat panel displays that can be electrically reconfigured between a full performance 2D mode and a low cross talk autostereoscopic 3D mode. The solid phase microlens array enables significant reductions in device thickness and improved ruggedness compared to nematic phase liquid crystalline mic...
متن کاملPolarizer-free liquid crystal display with electrically switchable microlens array.
We propose a polarizer-free liquid crystal display (LCD) with an electrically switchable microlens array. The incident lights are controlled to focused or defocused states by index matching of the lens polymer and LC layer. By adopting two light-blocking masks that have a circular stop pattern and the complementary open pattern, the LCD was able to realize the entire gray scale. Additionally, t...
متن کاملTunable liquid-filled microlens array integrated with microfluidic network.
An elastomer-based tunable liquid-filled microlens array integrated on top of a microfluidic network is fabricated using soft lithographic techniques. The simultaneous control of the focal length of all the microlenses composing the elastomeric array is accomplished by pneumatically regulating the pressure of the microfluidic network. A focal length tuning range of hundreds of microns to severa...
متن کاملTunable-focus liquid microlens array using dielectrophoretic effect.
A tunable-focus liquid microlens array based on dielectrophoretic effect was demonstrated. In a lens cell, two immiscible dielectric liquids but with different dielectric constants are sandwiched between electrodes. One electrode has a holed pattern while the other electrode is continuous. The applied voltage generates an inhomogeneous electric field near the hole regions. Owing to such an elec...
