    摘要： This invention relates to a helmet mounted display system of the kind comprising: a helmet having a transparent spherical visor (5) and an optical system (1, 7) which directs rays of light from a display produced by a display source (1) onto the visor to provide by reflection at the visor, at a helmet wearer's eye position (7), a collimated virtual image of the display on a line of sight of a wearer of the helmet through the visor.
    In order to facilitate adjustment of the eye position with respect to the helmet the visor is rotationally symmetrical about an axis about which the optical system is rotatable.
    The visor is preferably also rotationally symmetric about a second axis about which the visor is arranged to be rotatable between inoperative and operative positions.
    The invention finds particular application to binocular helmet mounted display systems, the two optical systems being then suitably arranged to be rotated relatively about a common axis with a scissors action, thereby to vary the spacing between the eye positions of the two display systems.

    摘要翻译： 技术领域本发明涉及一种头戴式显示系统，其包括：具有透明球形遮阳板（5）的头盔和将来自由显示源（1）产生的显示器的光线引导到其上的光学系统（1,7） 护目镜通过在遮阳板上的反射，在头盔佩戴者的眼睛位置（7）提供，通过遮阳板在头盔的穿戴者的视线上显示的准直虚拟图像。 为了便于相对于头盔的眼睛位置的调节，遮阳板围绕光学系统可旋转的轴线旋转对称。 遮阳板优选地围绕第二轴线旋转对称，围绕所述第二轴线，所述遮阳板布置成可在不操作位置和操作位置之间旋转。 本发明特别适用于双目头盔安装的显示系统，然后两个光学系统被适当地布置成相对于剪刀动作的公共轴线相对旋转，从而改变两个显示系统的眼睛位置之间的间隔。
