Abstract

Since their introduction a number of years ago, head up and helmet mounted displays have undergone continuous and intensive development in aerospace applications. To date, the designs have been performed using geometric optic design techniques and have progressed to the point where very little further improvement in their characteristics is possible. This paper describes a display realised by the use of new optical design techniques based on wave-guiding principles that have enabled substantial further significant improvements to be made. These improvements are not only in respect of size, weight and volume for a given optical performance, but also in the optical characteristics that currently limit the usability of such displays in many applications. Displays that have been realised and tested through these methods are described and their performance in laboratory and flight trials discussed, together with considerations for further progress in their development.
