摘要： A method for forming a multi-layered, stacked grid structure includes aligning a first grid structure with a second grid structure, wherein both the first grid structure and the second grid structure each include a substrate in which a plurality of trenches are formed and a cured carrier fluid disposed within the plurality of trenches, and wherein a plurality of nano-particles are suspended within the cured carrier fluid. The method also includes, upon aligning the first grid structure and the second grid structure so that their respective plurality of trenches are aligned in the same orientation, joining the first grid structure and the second grid structure together to form the multi-layered, stacked grid structure.

摘要： Disclosed is an improved diffraction structure for 3D display systems. The improved diffraction structure includes an intermediate layer that resides between a waveguide substrate and a top grating surface. The top grating surface comprises a first material that corresponds to a first refractive index value, the underlayer comprises a second material that corresponds to a second refractive index value, and the substrate comprises a third material that corresponds to a third refractive index value. According to additional embodiments, improved approaches are provided to implement deposition of imprint materials onto a substrate, which allow for very precise distribution and deposition of different imprint patterns onto any number of substrate surfaces.

摘要： A projector includes a laser module for generating a laser beam and a wafer-level optics. The wafer-level optics includes a first substrate, a first collimator lens and a diffractive optical element, wherein the first collimator lens is manufactured on a first surface of the first substrate, and is arranged for receiving the laser beam from the laser module to generate a collimated laser beam; and the collimated laser beam directly passes through the diffractive optical element to generate a projected image of the projector.

摘要： In a spectroscopic module 1, a flange 7 is formed integrally with a diffraction layer 6 along a periphery thereof so as to become thicker than the diffraction layer 6. As a consequence, at the time of releasing a master mold used for forming the diffraction layer 6 and flange 7, the diffraction layer 6 formed along a convex curved surface 3a of a main unit 3 can be prevented from peeling off from the curved surface 3a together with the master mold. A diffraction grating pattern 9 is formed so as to be eccentric with respect to the center of the diffraction layer 6 toward a predetermined side. Therefore, releasing the mold earlier from the opposite side of the diffraction layer 6 than the predetermined side thereof can prevent the diffraction layer 6 from peeling off and the diffraction grating pattern 9 from being damaged.
