摘要：The method comprises the steps of determining the separation betweeninterference pattern planes tangent to surfaces separated by a desired distance whichachieves desired optical properties at a given first wavelength and angular orientation oflight in a hologram disposed on a curved surface. The angular characteristics of exposureto achieve this separation of planes in a planar analog of the desired curved holographicelement is determined. A source is constructed having the desired angular exposurecharacteristics and having a second wavelength, the source being constructed using a pairof source sets which are activated in sequence to make the desired interference patternwhile shading parts of the substrate. An interference pattern is recorded in a

photosensitive substantially planar film using the constructed source. The developedinterference pattern acts as a transmission hologram. The removed sensitive layer is thenadhered to a substrate having the curved shape.
