Abstract : A second generation WAVIDS (Wide Angle Virtual Image Display System) has been designed using Fresnel lenses. The instantaneous field of view is 75 degrees, and the total field of view is 90 degrees, with an eye-clearance of 38.0 inches. The correction of spherical aberration, coma and astigmatism leads to a design with 30% negative distortion. An auxiliary optical system has, therefore, been designed which takes an undistorted image and introduces a compensating 30% distortion. As a result an undistorted image is viewed through the WAVIDS.
