We demonstrate an in-line digital holographic microscopy using a consumer scanner. The consumer scanner can scan an image with 4,800 dpi. The pixel pitch is approximately 5.29 μm. The system using a consumer scanner has a simple structure, compared with synthetic aperture digital holography using a camera mounted on a two-dimensional moving stage. In this demonstration, we captured an in-line hologram with 23, 602 × 18, 023 pixels (≈0.43 gigapixels). The physical size of the scanned hologram is approximately 124 mm × 95 mm. In addition, to accelerate the reconstruction time of the gigapixel hologram and decrease the amount of memory for the reconstruction, we applied the band-limited double-step Fresnel diffraction to the reconstruction.

nanostructured interferogram holography metasurfaces, which is among the various metasurfaces, can govern light in its propagation by surface waves or freespace waves and generate desired arbitrary optical images, [5,6] leading to various applications such as multilevel optical switching, [7] beam shaping, [8] plasmonic lens, [9] optical vortex beams detector, [10] laser tweezers, [11] data storage, [12] 3D holographic displays, [13,14] and high polarization conversion efficiency. [15] Therefore, these new types of holography metasurfaces have offered attractive functionalities for developing new types of optoelectronic devices. However, the holography metasurfaces are constrained by sophisticated design and fabrication procedures and are less compatible with dynamic functionalities as well as unequal across the electromagnetic spectrum. [16] Consequently, the creation of new optical holography metasurfaces that can be adjusted at will and integrated into optoelectronic systems would help to bridge the chasm between our macroscopic world and application based on this fascinating emerging field of microscopic systems.Nowadays, interest in the application of white organic lightemitting diodes (WOLEDs) for solid-state lighting and flat-panel display backlightings has been steadily increasing. [17][18][19] The maximum scientific reported power efficiency (PE) of WOLEDs has exceeded 100 lm W −1 beyond fluorescent tude efficiency for both rigid and flexible devices. [20][21][22] However, it is difficult for WOLEDs to compete in fields where concentrated or collimated ultrahigh luminous flux is needed. For example, they cannot operate in car headlights, general lighting retrofit bulbsor or flashlights. [23] Additionally, the intrinsically large-area light emitting characteristic limits the effectiveness of them in the luminance enhancment of liquid crystal displays (LCDs) as backlighting sources. [24] Therefore, tailoring broadband directive emission profile for WOLEDs by wavefronts shaping technology is extremely appealing and scientifically curious for aforementioned specific applications.Similarly, wavefronts shaping has also been attractive research direction for optical diffusers, which are widely used in the optical industry for distributing or spreading the light intensity. [25] One of the most common applications of optical diffusers is the backlighting system of the LCDs. Nevertheless, an additional prism sheet is usually added to limit the scattering angle of the light beams due to the poor light steeringThe advent of holography metasurfaces unlocks a plethora of exciting opportunities for rapid progress at the frontiers of various branches of science and engineering. However, the holography metasurfaces are constrained by sophisticated design and fabrication procedures and are less compatible with dynamic functionalities as well as unequal across the electromagnetic spectrum. Here, a new approach is proposed to fabricate speckle image holography metasurfaces with chaotic carrier fringes for broadband photon m...
