The present invention provides a colored radiative cooler based on a Tamm structure, including a substrate on which metal film and dielectric layers A to G are sequentially provided from bottom to top, where the Tamm structure is formed from the metal film and the dielectric layers A to D; a distributed Bragg reflector is formed from the dielectric layers A to D; and a selective emitter is formed from the dielectric layers E to G. Compared to the conventional radiative cooler, the colored radiative cooler not only has better cooling performance, but it has a wide applications in many aspects such as aesthetics and decoration.

The present disclosure discloses a real-time micro/nano optical field generation and manipulation system and method. The system comprises a light source, a spatial filtering unit, an optical 4F system and a light wave manipulation unit, and the optical 4F system comprises a first lens (set) and a second lens (set) sequentially arranged along a light path. The present disclosure achieves real-time modulation on an incident wavefront through a phase element or a phase element assemble. By dynamically manipulating an incident light sub-wavefront, or the light wave modulation optical element, or different areas of the optical element, or different parts of the optical field in an imaging plane and/or the like by the spatial filtering unit, real time light fields with different parameters are generated in the image plane of the system. By spatial filtering/spatial time division filtering/spatio-temporal multiplexing filtering and/or the change of the phase elements, flexible manipulation on patterns, pattern distribution areas and structural parameters such as the patterns' frequency, their orientations, duty ratios, phases or phase shifts and the like are realized. The system can be flexibly integrated into various lithography or microscopy systems for real-time micro/nano structure fabrication and dynamical or 3D detection with a real time manipulated structural illumination.

A multi-view pixel directional backlight module and a naked-eye 3D display device are provided. The multi-view pixel directional backlight module includes at least two rectangular light guide plates closely stacked together. A light-emerging surface of the rectangular light guide plate is provided with multiple pixel arrays. Light emitted by pixels in a same pixel array is pointed to a same viewing angle, and different pixel arrays have different viewing angles. At least one side of each rectangular light guide plate is provided with a light source group. Light emitted by the light source group enters the corresponding light guide plate, then emerges from pixels of respective pixel arrays on the light-emerging surface of the light guide plate, and is totally reflected at positions other than positions of the pixels within the light guide plate. Each of the pixels is a nano-diffraction grating.

A method for making a color image and a color filter manufactured with the method. The color of the color image and the color of the color filter are characterized by resonance features of a Fabry-Perot resonant cavity (). Through a nanoimprint technology, Fabry-Perot resonant cavities with different thicknesses are manufactured, and the Fabry-Perot resonant cavities with different thicknesses correspond to red, green and blue respectively. The red, green and blue Fabry-Perot resonant cavities are distributed according to the color separation principle, and a combination thereof has the effect of representing a whole image macroscopically.
