ABSTRACT:
A concave Fresnel mirror, suitable for use in image display systems. With proper orientation of the facet slopes of the Fresnel mirror, the angular field presentation to the eye will represent a constant magnification for all points in the object space at the nominal eye position determined from the intended application of the invention. This invention provides a numerical means to determine the facet slopes of off-axis Fresnel reflectors using commonly available spreadsheet software which is then easily transformed into numerical control data for cutting the desired configuration.
