  1. 1. Diffractive Optical Elements: Fabrication, Replication, and Applications and Optical Properties of a Visual Field Test

    Author : Fredrik Nikolajeff; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; perimetry; beam homogenizing; antireflection; high-pass spatial frequency target; proximity effect; electron beam lithography; replication; successive development; diffractive optical element; axicon;

    Abstract : This thesis mainly treats the fabrication, replication and applications of diffractive optical elements. A smaller part deals with optical properties of a visual field test. Diffractive optical elements are computer-generated micro-optic components that use diffraction to manipulate light. READ MORE
