Head Up Display Performance Improvements and Cost Reductions through the Application of Non-conventional Engineering Solutions

This paper describes displays realized by the use of radically new optical and image source design techniques that have facilitated very significant performance improvements beyond those previously achieved.

These improvements are not only in respect of size, weight, volume and cost for a given optical performance, but also in the characteristics that currently limit, or in some cases prohibit, the use of such displays in many cockpit applications. Displays that have been realized and tested through the implementation of these new techniques are described and their performance in laboratory and flight trials discussed, together with a discussion of the way ahead for further progress in their development.
