摘要
Holography has attracted tremendous interest due to its capability of storing boththe amplitude and phase of light field and reproducing vivid three-dimensionalscenes. However, the large pixel size, low resolution, small field-of-view (FOV) andlimited space-bandwidth of traditional spatial light modulator (SLM) devices restrictthe possibility of improving the quality of reconstructed images. With thedevelopment of nanofabrication technologies, metasurfaces have shown greatpotential in manipulating the amplitude, phase, polarization, frequency orsimultaneously multiple parameters of output light in ultrashort distance withsubwavelength resolution by tailoring the scattering behaviour of consistednanostructures. Such flexibilities make metasurface a promising candidate forholographic related applications. Here, we review recent progresses in the field ofmetasurface holography. From the perspective of the fundamental properties oflight, we classify the metasurface holography into several categories such as phaseonlyholography, amplitude-only holography, complex amplitude holography and soon. Then, we introduce the corresponding working principles and design strategies.Meanwhile, some emerging types of metasurface holography such as tunableholography, nonlinear holography, Janus (or directional related) and bilayermetasurfaces holography are also discussed. At last, we make our outlook onmetasurface holography and discuss the challenges we may face in the future.
