Development of holographic solar concentrator using holographic optical elements

Digital Holography and Three-Dimensional Imaging, 2016
In this paper, we present the development of holographic solar concentrator using holographic optical elements (HOE). The transmission HOE was evaluated by measuring the optical efficiencies of holographic gratings recorded at 532 nm wavelengths. We experimentally confirmed that holographic solar concentrator can condense the wide angle light to a ...

Holographic solar concentrator using multiplexed holographic optical elements

2018 23rd Opto-Electronics and Communications Conference (OECC), 2018
In this paper, we present the multiplexed holographic optical elements (HOEs) using photopolymer for solar concentrator application. We experimentally confirmed that multiplexed holographic lens can condense the lights with high optical efficiency.

Achromatic Holographic Optical Elements

Journal of Optics, 1978
It is shown that the holographic optical elements (HOE) can be achromatised to be used with polychromatic light. The two-elements and three elements achromatic HOE systems possess negative power and hence should be used in conjunction with refractive/reflective optics.

Programmable holographic elements for WDM

IEE Colloquium on Optoelectronic Integration and Switching, 1997
We describe the results of a new wavelength-division-muitiplexing (WDM) technology for use in optical telecommunications. A polarisation-insensitive ferroelectric liquid crystal (FLC) spatial light modulator (SLM) acting as a programmable holographic element in conjunction with a highly wavelength-dispersive fixed diffractive element has been used to ...
