In this utility model embodiment, shown using first surface to better illustrate in this utility model embodiment
The concept of the curvature of field and astigmatism in beneficial effect after screen 104 and the second camber display screen 105, first explanation prior art.
The impact to described wear-type virtual reality device for the astigmatism is described taking Fig. 2 as a example, extra-axial object point light pencil is imaged
When, formation two is mutually perpendicular to and a kind of asymmetry aberration of short-term picture separated by a distance is referred to as astigmatism, in Fig. 2 thoroughly
The edge of mirror can be divided into the horizontal edge of lens and the vertical edge of lens according to the primary optical axis of lens, and light path A is from institute
State the incident collimated light beam of vertical edge, in V, V is meridional focus to imaging point, light path B is from incident the putting down of described horizontal edge
Row light beam, in H, H is sagittal focuss to imaging point.Meridional focus and sagittal focuss are not same point, as astigmatism, and astigmatism is with visual field
Increase and increase rapidly that is to say, that the imaging at horizontal direction edge seen by described wear-type virtual reality device of people
Imaging with vertical direction edge in a focus, can not cause soft edge.
The impact to described wear-type virtual reality device for the curvature of field is described, in Fig. 3, light path 1 is and lens light taking Fig. 3 as a example
The parallel paraxial beam of axle incides the light in lens, and light path 2 is incident through the larger directional light in the visual field of rims of the lens
Light in lens, the optimal picture point that described light path 1 is formed is O point, and the optimal picture point that light path 2 is formed is T point, rather than and O
Point in conplane F point that is to say, that through rims of the lens light optimal imaging point near lens centre light
Not in approximately the same plane, that is, seen by person is optimal imaging face to good imaging point, is not a vertical O-F plane, but
Curved surface through O-T point.In large visual field optical system, the curvature of field certainly exist so that image objects the most clearly face be not one
Individual plane but a curved surface, and control plus astigmatism and improperly affect, picture quality can be worse.
So leading to be imaged unsharp problem, this practicality to solve astigmatism present in above prior art and the curvature of field

The edge point position of curtain, B is with a bit on angle of visual field first surface display screen 104 or on the second camber display screen 105, C with A
Marginal position for same size curve screens is it is seen that the Curved screen of same level size is bigger than the plane screen angle of visual field..
In this utility model embodiment, due to B with respect to A point closer to the first optical glass 107 or the second optical frames
Piece 108, defines according to aplanatism principle, and B point is apparent with respect to A point, that is, improve described wear-type virtual reality device
Imaging definition.Meanwhile, consider human eye in this visual system more more sensitive than vertically to level, according to sagittal focuss and meridian
The position relationship of focus, i.e. the curvature of astigmatism parameter adjustment Curved screen, can improve the definition of image planes further.As Fig. 5 is
Example, A point is the marginal point on paraxial optimal imaging face, this near sagittal focuss, but away from meridional focus, its result be people soon
The picture arriving is more clear in the horizontal direction, but vertical direction deforms.And the edge B point of same size Curved screen is with respect to A
Point, position is between meridional focus and sagittal focuss that is to say, that decreasing the deformation in vertical direction for the picture point, improves
The definition of big visual field hypograph.
