Abstract
The invention relates to compact optical arrangement for a helmet mounted display. The arrangement is well suited to use with spatial light modulators which require front illumination such as LCoS modulators but can also be adapted to rear illuminated devices such as LCD's and to self luminous devices such as OLEDs. The device uses polarization and reflection to make dual use of both volumes and lenses.
