A two-axis single holographic lens element is evaluated as to its quality in the areas of diffraction efficiency, resolving power, Hartmann graphs, spherical aberration, coma, astigmatism, field curvature, distortion, chromatic aberration, and angle of diffracted light. The holographic element is shown to be satisfactory for a virtual image display in all areas except chromatic aberration.
