Holographic window coatings for solar control and daylighting: Assessment report
Abstract
Control of sunlight passing through windows based on the diffraction of light is investigated. In this approach, holographic optical elements (HOE's) intercept sunlight and diffract it in a desired direction. As a window coating that may be applied to an existing structure, a HOE can provide angular acceptance or rejection of the incoming sunlight, can direct sunlight deeply into a room to provide task lighting, and can select the portion of sunlight with the greatest visual efficacy. Possible uses include daylighting, sunlight control and rejection, and solar heating.
