    摘要: There is provided a frameless display device in which a frame on the periphery of a display portion is made invisible. The frameless display device makes the frame on the top surface of a button 8 invisible to display an image on the entire surface of the button 8, wherein the button 8 has a lens 9 and a button cover 8A, wherein a display device 6 is provided below the lens 9, and wherein the lens 9 disposed on top of the button 8 includes a curved surface 9A formed on the periphery of the top surface of the lens 9, a depression formed on the bottom surface of the lens, a step formed at the periphery of the lens, and an inclined surface formed at the step and inclined towards the center of the lens 9.

    摘要: This invention in phase homogenization of coherent light from illuminators used for surveillance imaging systems provides a coherent light emitter aligned with a light source ray path along an optical axis with at least two separated microdiffractive diffusers, the microdiffractive diffusers comprising holographically generated surfaces of microdiffractive structure that statistically tend to diffract light at selectable angles or distribution patterns, the microdiffractive diffusers disposed upon a substrate and separated from each other by a distance determined by wavelength phase and irradiance characteristics of the coherent light emitter and by refractive characteristics of at least two microdiffractive diffusers, followed by a homogenized exit ray path in order to produce a diffused pattern of illumination optimized for long distance surveillance imaging.
