Abstract
An optical diffusing element includes a light emitting surface. The light emitting surface has microstructures, each microstructure has a border, the border of each microstructure is completely connected with the borders of the adjacent microstructures, each microstructure has a surface profile, and a functional formula of the surface profile is: s(x) represents the surface profile of each microstructure on an x-axis. The value x represents a vertical projection position of the surface profile on the x-axis. The value R represents a curvature radius of a vertex of each microstructure. The value κ represents a conic coefficient of each microstructure. The microstructures have the same value R and value κ. A light emitting assembly for three-dimension sensing includes the optical diffusing element and a light source. The optical diffusing element and the light emitting assembly for three-dimension sensing have the advantages of controlling light shape, light profile and simplifying design.
