摘要： An optics component with double-layered micro-lens array includes mainly complex pinhole structures in array arrangement on one substrate face, and either substrate face has an optical micro-lens array. Both optical micro-lens arrays include a plurality of aspheric micro-lenses corresponding to the pinhole structures. When the component is in use, a UV light reflected by a DMD wafer is focused onto each pinhole structure through the plurality of aspheric micro-lenses in the optical micro-lens array of one face of a crystal substrate, and a small spot is formed, which may begin to diffuse after passing through the pinhole structure. Then, the beam is focused onto another face by the plurality of aspheric micro-lenses of another substrate face to obtain a small spot with a small circular spot approaching physical diffraction limit. The formed spot arrays can be applied to the scanning maskless and direct-write exposure lithography process.

摘要： A method for producing patterns in a layer to be etched, from a stack including at least the layer to be etched and a masking layer overlying the layer to be etched, with the masking layer having at least one pattern. The method includes modifying a first area of the layer to be etched by ion implantation through the masking layer; depositing a buffer layer to cover the pattern of the masking layer; modifying another area of the layer to be etched, different from the first area, by ion implantation through the buffer layer, to a depth of the layer to be etched greater than the implantation depth of the preceding step of modifying; removing the buffer layer; removing the masking layer; removing the modified areas by etching them selectively to the non-modified areas of the layer to be etched.

摘要： Spatio-temporal light field cameras that can be used to capture the light field within its spatio temporally extended angular extent. Such cameras can be used to record 3D images, 2D images that can be computationally focused, or wide angle panoramic 2D images with relatively high spatial and directional resolutions. The light field cameras can be also be used as 2D/3D switchable cameras with extended angular extent. The spatio-temporal aspects of the novel light field cameras allow them to capture and digitally record the intensity and color from multiple directional views within a wide angle. The inherent volumetric compactness of the light field cameras make it possible to embed in small mobile devices to capture either 3D images or computationally focusable 2D images. The inherent versatility of these light field cameras makes them suitable for multiple perspective light field capture for 3D movies and video recording applications.
