A Study on Augmented 3D Display Optimization Based on Holographic Optical Element for High Depth and Magnified Image [PDF]

open access: yesFrontiers in Physics, 2021
Modern Pepper's ghost—“floating hologram”—systems generally use transparent screens called half mirrors or foils. this system must have the same screen size as the image size in order to display a large-sized image. Further, depth of the image can only be obtained from the distance between the screen and the display panel.

Left and Right Magnifying Elements in the Semigroup of all Binary Relations

open access: yesEuropean Journal of Pure and Applied Mathematics, 2020
An element a of a semigroup S is called left [right] magnifying if there exists a proper subset M of S such that S = aM [S = M a]. Let X be a nonempty set and BX the semigroup of binary relations on X. In this paper, we give necessary and sufficient conditions for elements in BX to be left or right magnifying.
