Abstract : An optical design study was undertaken with the objective of conceiving and proving feasibility of an optical system which would provide a 25 degree binocular field of view for a typical head-up aircraft cockpit display. Preliminary work in evaluation of several novel concepts showed that a system using two concave ellipsoidal reflectors with a common focus and several refracting elements showed considerable promise. Existing computer programs were not adequate to evaluate the image-forming capability of such a system. Therefore, it was necessary to devise a new computer program which would permit the design, utilizing automatic correction and the evolution of this complex type optical system. (Author)
