Short coherence laser interferometer measures transparent domes

July 14, 2020
Combining a short coherence source with an adjustable path-match mechanism makes it possible to isolate and measure the front and back surfaces of transparent components as thin...

OPTICS FOR SOLAR ENERGY: Holographic planar concentrator increases solar-panel efficiency

Dec. 1, 2008
In a holographic planar concentrator, holographic film diffracts usable frequencies of sunlight, and guides that energy toward strips of solar cells, resulting in a solar module...
