It is to be understood that：In the figure 7, E0The element E1 with reflection function is added between concave mirror R, is schemed
7 be one of example, is not the protection domain and authority for limiting this patent, can essentially be in E0And concave reflection
One or more elements with reflection function are added between mirror R, can equally realize the effect for the display that suspends.In order to eliminate ring
The influence of border light and glare, polarizer (linear polarization or circuit polarizer), a quarter can also be added in above-mentioned light path
Wavelength retarder etc..
Based on above-described embodiment, the face type of each lens in the optics module is to be set according to actual conditions using optics
Meter software or algorithm obtain.
Specifically, by taking the structure shown in concave mirror and conventional lenses group and Fig. 1 as an example, in optimization design concave reflection
During the face type of mirror and each lens, it is necessary first to it is determined that display source M1Center and compound lens group M2Middle first lens center
Distance LO；Compound lens group M2Middle k-th lens centre and element E0The distance L at center1；Element E0Center is to compound lens group
M2' the distance L of middle n-th lens centre2；Compound lens group M2' in the 1st lens centre and concave reflection R centers distance L3
And element E0Center is to suspended images M3In distance LI.Secondly the size and viewing visual angle of suspended images are determined, is finally determined multiple
Close the quantity of lens in lens group.
The above is all the whole system desired value to be optimized, and to reach these desired values,
Need constantly to iterate to calculate using optimized algorithm after selected optimized variable, finally give and meet each of desired value
The value of optimized variable and specific face shape parameter.The optimized variable of the system has：Thickness, the adjacent optical eyeglass of each optical mirror slip
Spacing, face type formula (including each change in formula that is followed of the material selected of optical mirror slip and each optical mirror slip
Amount：Curvature, asphericity coefficient etc.) (can be existing sphere or aspherical face type formula, also or user-defined face type
Formula).Table 1 is the parameter for the concave mirror being calculated according to the method described above, and table 2 is calculated according to the method described above
Compound lens group M2、M2' parameter of one of optical mirror slip is as shown in table 1, is wherein one be calculated according to the method described above
The parameter of individual optical mirror slip.
Table 1
Table 2
The face type formula that optical element follows in table 1, table 2 is as follows：
Wherein, Z is the rise of lens, and c is curvature, and r is radial direction bore, and k is circular cone coefficient, and a1~a5 is aspherical system
Number.
Embodiment above is a kind of possibility therein, in fact, the change of system optimization desired value, optimized variable
The change of selection, the change of optimization order, the selection (selection of built-in variable) of face type formula and optimized algorithm selection can obtain
Go out different variate-values and face shape parameter, therefore have the result of the numerous face shape parameter for meeting to require.These other face types
Can also be the Fresnel Lenses equivalent with it.These belong to industry personnel and existed without creative efforts
With reference to that can obtain different face shape parameters after above-described embodiment by modification, these should belong to the protection model of this patent
Enclose.
Finally it should be noted that：The above embodiments are merely illustrative of the technical solutions of the present invention, rather than its limitations；Although
The present invention is described in detail with reference to the foregoing embodiments, it will be understood by those within the art that：It still may be used
To be modified to the technical scheme described in foregoing embodiments, or equivalent substitution is carried out to which part technical characteristic；
And these modification or replace, do not make appropriate technical solution essence depart from various embodiments of the present invention technical scheme spirit and
Scope.
