Really, virtual three-dimensional Projection Display and observing effect are inferior to, in projection type virtual reality system, Helmet Mounted Display is used as system work(
A kind of supplement and auxiliary that can be with equipment.
The principle of Helmet Mounted Display is to amplify the image produced by small two-dimension display by optical system.It is specific and
Speech, the light that miniscope is launched makes image produce similar distant place effect because of refraction by convex lens.Utilize this effect
Near objects are amplified to and views and admires at a distance and reaches so-called full figure vision.The image of liquid crystal display is eccentric free by one
Toroidal lens, makes image become similar big screen picture.Because eccentric free-form surface lens are a skewed concave lens, therefore
Optically it has not been singly lens function, substantially turns into scope of freedom prism.When the image of generation enters eccentric freely bent
Face prism facets, then be all-trans and be incident upon observer's eyes oncoming lane concave surface minute surface.Side concave surface minute surface scribbles one layer of reflecting layer, and reflection is same
When light be exaggerated reflex to eccentric free curved surface prism face again, and the Ray obliquity that makes corrections in the face reaches observer's eyes.
The maintenance of Helmet Mounted Display can extend the service life of Helmet Mounted Display, and current virtual implementing helmet display is protected
Foster equipment haves the shortcomings that complicated, cumbersome, therefore needs a kind of virtual reality simple in construction, easy to operate of research and development badly
Helmet Mounted Display maintenance facility.
