Moiré is an appealing visual effect observable when two or more repetitive patterns are superposed. We introduce a method for designing and fabricating level-line moirés on curved surfaces. These moiré shapes are obtained by superposing a partly absorbing or partly light deviating curved base layer and a curved revealing layer formed by a grating of transparent lines or cylindrical lenses. The distances between base layer and revealing layer are adapted to the locally varying distances between successive transparent lines or cylindrical lenses of the curved revealing layer grating. We demonstrate the quality of our method by rendered simulations and by fabrication. The resulting level-line moiré display devices can be manufactured using different fabrication techniques, from multi-material 3D printing to molding.

A display device includes a display panel that emits light from a plurality of pixels arrayed at predetermined pixel array pitches and an optical film, placed over the display panel so as to allow passage of light from the plurality of pixels, that includes first and second optical functional parts differing in optical performance from each other. The first and second optical functional parts are arrayed at predetermined functional part array pitches. Assuming that p (μm) denotes the pixel array pitches, that q (μm) denotes the functional part array pitches, and that d (μm) denotes a distance in a face-to-face direction between surfaces of the pixels that face the optical film and a surface of the optical film that faces the pixels, q≤0.5p and tan(asin(0.7/q))<p/d hold.

The technology disclosed relates to structured illumination microscopy (SIM). In particular, the technology disclosed relates to capturing and processing, in real time, numerous image tiles across a large image plane, dividing them into subtiles, efficiently processing the subtiles, and producing enhanced resolution images from the subtiles. The enhanced resolution images can be combined into enhanced images and can be used in subsequent analysis steps.
