摘要： A laminate which can serve as either a smart window or a smart mirror is formed using first and second substrates coated with transparent first and second electrodes which are separated by foraminous layer and a third grid-like linear electrode insulated from the first and second electrodes. The foraminous layer includes spacers defining a cell space which is filled with a colloidal ink having first and second particles. The first particles have a positive charge and a first color and second particles having a negative charge and a second color different from the first color. By altering the voltages of the first, second and third electrodes, one can achieve different light transmission characteristics which, for example, can alter the color temperature of the light transmitted through the laminate or enhance reflective colors.

摘要： Shape measurement of a specular object even in the presence of multiple intra-object reflections such as those at concave regions of the object. Silhouettes of the object are extracted, by positioning the object between a camera and a background. A visual hull of the object is reconstructed based on the extracted silhouettes, such as by image capture of shadows of the object projected onto a screen, and image capture of reflections by the surface of the object of coded patterns onto the screen. The visual hull is used to distinguish between direct (single) reflections of the coded patterns at the surface of the object and multiple reflections. Only the direct (single) reflections are used to triangulate camera rays and light rays onto the surface of the object, with multiple reflections being excluded. The 3D surface shape may be derived by voxel carving of the visual hull, in which voxels along the light path of direct reflections are eliminated. For surface reconstruction of heterogeneous objects, which exhibit both diffuse and specular reflectivity, variations in the polarization state of polarized light may be used to separate between a diffuse component of reflection and a specular component.

摘要： A reflective liquid crystal display device includes a first substrate provided with a reflective electrode, a second substrate provided with a transparent electrode, a liquid crystal layer disposed between the first substrate and the second substrate, and an anisotropic scattering member formed on the second substrate. The anisotropic scattering member has first and second surfaces each including a first refractive index region and a second refractive index region having a refractive index different from that of the first refractive index region. A refractive index difference between the first refractive index region and the second refractive index region in the first surface is larger than that in the second surface. The anisotropic scattering member is disposed so that light enters from the first surface thereof and the light exits as scattered light from the second surface thereof. A phase difference is given to the light entered the anisotropic scattering member.

摘要： The general field of the invention is that of optical viewing systems comprising a display and a tilted optical plate arranged above this display and forming therewith substantially a dihedron. The system according to the invention comprises means for adjusting the reflection coefficient of the said tilted optical plate along an axis perpendicular to the axis of the dihedron and up to a variable height so as to ensure the total reflection of a first part of the image displayed by the display and the partial reflection of a second part of the image displayed by the display, complementary to the first part. The insertion of optical components between the display and the optical plate makes it possible to modify the distance of the display image reflected by the optical plate.

摘要： A means of forming unevenness for preventing specular reflection of a pixel electrode, without increasing the number of process steps, is provided. In a method of manufacturing a reflecting type liquid crystal display device, the formation of unevenness (having a radius of curvature r in a convex portion) in the surface of a pixel electrode is performed by the same photomask as that used for forming a channel etch type TFT, in which the convex portion is formed in order to provide unevenness to the surface of the pixel electrode and give light scattering characteristics.
