Holographic Solar Energy Concentrator Using Angular Multiplexed and Iterative Recording Method
IEEE Photonics Journal, 2016 Holographic optical elements can be fabricated to concentrate the solar energy with no sun tracking system. Concentrated diffraction efficiency (CDE) for the holographic solar concentrator is suggested as a new efficiency calculation method. The exposure

Holographic optical scanning elements with minimum aberrations [PDF]
Applied Optics, 1988 An analytical method to design holographic optical elements for focusing laser scanners, especially disk scanners, with minimum aberrations and optimum scan line definition is reported. The results reveal that the focused spot constraint to a straight line is always astigmatic.
