    Sammanfattning : This thesis treats design, manufacture, evaluation and applications of computer-generated surface relief holograms - kinoforms. These diffractive, phase-only, planar optical components are characterized by high efficiency, design flexibility, light weight and small size. They can further be reproduced at low cost. LÄS MER
