We analyze an image quality of a holographic lens (HL) in order to implement compact near-eye displays using a flat-panel-type micro-display panel. The proposed method utilizes a non-converging signal wave in a fabrication process of the HL, so that

We propose, what we believe to be, a novel assessment methodology for evaluating three-dimensional (3D) characteristics of an eye-box volume in a near-eye display (NED) using a light-field (LF) data acquired at a single measuring distance. In contras

In a fabrication of geometrical waveguides for near-eye displays, edges of elemental prisms forming an out-coupler are beveled unavoidably. The beveled edges distort the light propagation in the transmission path, and degrade the see-through property

The representation of three-dimensional volumetric pixels, voxels, is an important issue for the near-to-eye displays (NEDs) to solve the vergence-accommodation conflict problem. Although the holographic waveguides using holographic optical element (

Microbial electrolysis cells (MECs) at various cell voltages (0.5, 0.7 1.0 and 1.5V) were operated in anaerobic fermentation. During the start-up period, the cathode potential decreased from -0.63 to -1.01V, and CH4 generation increased from 168 to 1
