TopOwl® is an original concept of binocular Helmet Mounted Sight and Display system (HMSD) for helicopters, where
two Image Intensifier Tubes (IIT) are integrated on the headgear and optically coupled to the clear visor placed in front
of the pilot's eyes.
Thales recently developed a new version of its TopOwl®'s Display Module with the objective to have an HMSD capable
to achieve all kind of missions up to the darkest night levels. The main enhancements are the redesign of the optical
combination, the use of new optical materials and of latest generation of optical design tools.
Two flyable prototypes of this new design were manufactured. A performance assessment has been conducted, showing
a significant improvement of the night vision performances, reaching performances equivalent to those of last issued
NVGs. These evaluations are being completed by different flight test evaluations.
