Gentex Corporation presents experience with the first binocular implementation of its Scorpion Helmet
Mounted Display (HMD) System. Gentex has a working prototype for a binocular version of Scorpion,
using two Scorpion PD-14 displays mounted on a single helmet. The prototype has excellent
characteristics for a binocular helmet. The displays' optical characteristics make them easy to harmonize
and comfortable to use without eyestrain. The displays are light enough not to unduly affect the weight of
the helmet or center of gravity. Harmonization, which has been a significant problem with other binocular
display systems, is easy to achieve, and once achieved remains fixed without issue.
