A dual‐view one‐dimensional integral imaging display using parallax barrier is proposed. It is composed of a display panel, a parallax barrier, a polarized array, and two pairs of polarized glasses. The polarized array consists of two kinds of orthogonal polarized units that are alternately aligned. Two kinds of elemental images are aligned to the corresponding polarized units, respectively. The lights emitted from two kinds of elemental images are, respectively, modulated by the corresponding slits and polarized units, and two three‐dimensional (3D) images are simultaneously reconstructed in the viewing zone. Two pairs of orthogonal polarized glasses are introduced to separate two reconstructed 3D images. Only one of the two reconstructed 3D images is seen by wearing either pairs of polarized glasses. An experimental setup was developed, and the viewing angle of the dual‐view one‐dimensional integral imaging display is proportional to the aperture width of the slit. The restriction between the viewing angle and the optical efficiency is resolved in the proposed dual‐view one‐dimensional integral imaging display.

“…[ 5 ] However, the traditional lenses are either big‐size or heavy, and thus can hardly meet the trends in highly integrated systems. Microlenses and microlens arrays, which are widely used in imaging, [ 6–10 ] beam shaping, [ 11–14 ] sensing, [ 15–17 ] and compound eyes monitoring, [ 18–20 ] have attracted extensive attention due to the low weight and small footprint. Generally, they can be manufactured with dielectric or metallic metasurface, [ 21 ] binary optics, [ 22 ] or other diffractive optical elements (DOEs).…”

Microlenses and microlens arrays are one of the indispensable components in modern optical systems ranging from imaging and beam shaping to polarization control and switchable 2D/3D displays. Among them, the liquid crystal microlenses (LCMs) with size below 1 mm have attracted more and more attention due to their stimuli‐responsiveness and tunability in focal length and polarization. Compared with microlenses based on inorganic binary optics, diffractive optical elements, or metasurface, LCMs are more cost‐effective and can be easily tuned. In this paper, an in‐depth review of the design principles, fabrication techniques, emerging applications, and recent advances of LCMs and arrays is presented, aiming to clarify the characteristics, limitations, and challenges in LCMs design and fabrication. This review may provide directions for solving those challenges, and expand the applications of LCMs.

“…Interestingly, illumination via a grating nanostructure has also been employed in fields including optical communications, displays, and imaging systems. For example, visualization through a grating polarizer or pixelated polarizer array provides the orientation direction information on the reflected plane of an object, , eliminates reflections and glare on smooth surfaces, , enhances the contrast of scratches and stains, and helps in analyzing the distortion due to mechanical stress in transparent objects. Additionally, when incorporated with various optical stacks and arrangements, the grating polarizer has realized a dual-view three-dimensional display from one display panel , and a snapshot multispectral camera. , Apart from the pure polarization property at visible light wavelengths with a grating period of smaller than 200 nm, wire grid grating nanostructures have been reported in applications for their additional wavelength selection capability that varies with the grating period, incident angle, and nanostructure materials, including a single metal layer made of silver (Ag), gold (Au), or aluminum (Al) and a sandwich stack of dielectrics and metals. ,− …”

Overcoming the diffraction limit is a great challenge to increasing the nanowell density. A methodology differing from super-resolution microscopy is introduced to realize a theoretical √2or √3-fold resolution improvement via two-step imaging and simple equipment adaptations: (1) a biochip integrated with an orthogonal-orientation nano/micropolarizer array in an interspaced arrangement with reaction sites and (2) an optical system inserted with an angle-switchable polarizer plate to generate polarized light for illumination. Because the 0°polarized light will be blocked by the 90°polarizer units, only half of the signals on the polarizer array with the same polarization angle can be acquired, and a virtual distance occurs between any two "bright" fluorescence signals. We have demonstrated that a 0.9 μm pitch wide-field image unresolvable via a 20×/NA0.5 objective can be divided into two resolvable images with an 8−10 signal-to-noise ratio (SNR) based on this approach. The aluminum polarizer array on the biochip had a 180 nm thickness, 0.9 μm pixel size, 300 nm period, and ∼0.55 fill factor. This method could be used for practical fluorescence-based nanoarray analysis, such as next-generation sequencing (NGS), to either enlarge the field of view to accelerate the scanning speed of a whole chip or increase the reaction density for multiple throughputs, and thus the sequencing cost can be reduced.
