“…2D images can be achieved when the electric voltage is tuned to obtain a planar oil/water interface; while 3D vision can be achieved by forming a convex oil shape by increasing the voltage [140] (figures 10(a) and (b)). Similarly, lenticular display using elastomer-liquid lenses has been demonstrated by changing the hydrostatic pressures across the elastomer membranes of an array of elastomer-liquid lenses covered on pixelated images [141]. LC lenticular displays consist of a polymeric LC lenticular lens array, a polarizer, and a twisted-nematic (TN) cell [142,143] (figure 10(c)).…”

Optofluidic lenses that modulate light using fluidic materials have been recognized as a powerful alternative to solid lenses. These lenses can achieve many advanced imaging capabilities that are difficult to achieve otherwise. In particular, such adaptive optical elements have shown great potentials in a broad array of applications in two-dimensional (2D) and three-dimensional (3D) imaging, including macro/microscopic imaging, optical coherence tomography, wide-angle imaging, spectral imaging, optical zooming, and switchable monocular/binocular vision. This article reviews current research efforts on optofluidic lenses for 2D/3D imaging. The configurations and actuation mechanisms of different types of optofluidic lenses and their representative imaging applications are introduced. The opportunities and challenges in this field are also discussed. This review is expected to provide a snapshot of the current landscape of optofluidic lenses research to attract more interests in this exciting field and foster the development of next-generation optofluidic lenses.

Recently, a planoconvex structure electrowetting lenticular lens capable of 2D/3D conversion through a varifocal property by an electrowetting phenomenon has been developed. However, even though it has a similar planoconvex structure to that of a commercial solid lenticular lens, comparable 3D performance could not be realized because the refractive index difference between nonconductive liquid and conductive liquid was not large. Therefore, the goal of the present study is to obtain better 3D performance compared to the conventional planoconvex structure by introducing a novel biconvex structure using ETPTA. The newly developed biconvex structure electrowetting lenticular lens showed greatly improved characteristics compared to the planoconvex structure: dioptric power (171.69D → 1,982.56D), viewing angle (26degrees → 46degrees), and crosstalk ratio (27.27% → 16.18%). Thanks to these improvements, a fine 3D image and a natural motion parallax could be observed with the biconvex structure electrowetting lenticular lens. In addition, the novel biconvex structure electrowetting lenticular lens was designed to achieve a plane lens state with a no voltage applied condition, and as such it could show a clean 2D image at 0 V. In conclusion, a novel biconvex structure electrowetting lenticular lens showed 2D/3D switchable operation as well as excellent 3D performance compared to a solid lenticular lens.
