The virtual image lifts Consumer's Experience away from unification, and then improves the comfort level for wearing wear-type product, and the present embodiment is related to one kind and worn
Formula product optics module 100, it carries out the virtual image away from focusing, including eyeglass module 20 and screen mould using the virtual image away from test camera 10
Group 30；Eyeglass module 20 includes eyeglass 21 and eyeglass mounting cylinder 22, and eyeglass 21 is arranged on inside eyeglass mounting cylinder 22；Screen module
30 include screen 31 and lens barrel 32, and screen 31 is arranged on the bottom of lens barrel 32；Eyeglass module 20 is rotatable relative to screen module 30.
Specifically, realize the virtual image away from focusing, rotation eyeglass module 20, by the virtual image away from test camera 10 by the virtual image first
Away from imaging definition is observed in test camera 10, until reaching best sharpness, stop the rotation eyeglass module 20, the optics module
100 by adjust eyeglass module 20 realize the virtual image away from calibration so that the virtual image of optics module 100 away from unification so that with
Eyes can have the virtual image of unification away from raising user's perception when the wear-type product with the optics module 100 is worn at family
Experience.
In the present embodiment, in order to realize rotation of the eyeglass module 20 relative to screen module 30, as shown in figure 1, in mirror
External screw thread 22-1 is provided with the exterior side wall of piece mounting cylinder 22, and correspondingly, as shown in Fig. 2 in the top inner wall of lens barrel 32
It is provided with the internal thread closed with external screw thread 22-1（It is not shown）.As shown in figure 3, in the present embodiment, by eyeglass module 20 and screen
Curtain module 30 be assembled into after optics module 100, by the virtual image away to the defocused virtual image away from test camera 10 be erected at the light
Learn directly over module 100, it is optimal that rotation eyeglass module 20 realizes measuring resolution, complete the virtual image to the module 100 away from school
It is accurate.
Cause in the virtual image of the virtual image away from test 10 pairs of optics modules 100 of camera away from focusing from the virtual image away from test camera 10
It was observed that after optimal definition, fastening structure can be used（It is not shown）Solidify eyeglass module 20 and screen module 30, keep away
Exempt from eyeglass module 20 to further rotate relative to screen module 30, enhancing calibration reliability.In the present embodiment, in eyeglass module
Dispensing is to form glue layer between 20 and screen module 30（It is not shown）, realize solidification between the two.
In order to carry out test of the virtual image away from calibration, in this example, it is assumed that the design virtual image is away from for 2m, in optics module 100
The focal length of eyeglass 21 is 40mm, general assembling and monomer tolerance in the case where not adjusting object distance（Tolerance refers to eyeglass 21 and screen
The tolerance of distance between 31）Empirical value be ± 0.4mm, therefore according to object-image relation（WhereinFor object distance,For Jiao
Away from, s be the virtual image away from）, it is 1.1m-2.6m that can be corresponded to using simulation software Zemax and obtain the virtual image away from scope.The present embodiment virtual image is away from test
The focal length f of camera 10 is 100mm, and aperture-coefficient F is 3.5, and camera image confusion 3 μm of size of element allows circular diameterFor 6 μm, regulation is surveyed
The focal distance L for trying camera 10 is 2m, according to depth of field calculation formula,
Wherein,, byThe preceding depth of field for calculating camera 10 is 1992mm, by
It is 2008mm to calculate the depth of field thereafter, and the field depth for obtaining camera 10 is 2000mm ± 8mm.Void can be drawn according to object-image relation
The corresponding relation of image distance and object distance, assembly precision be the virtual image away from the corresponding object distance ranges of precision ± 8mm.By rotating eyeglass mould
Group 20 adjusts the distance between eyeglass 21 and screen 31（That is object distance）, the object distance of module 100 and the relation of definition can be obtained,
As shown in figure 4, wherein definition refers to optical transfer function, obtained by emulation and done the definition at normalization
Reason.According to the as above virtual image away from the corresponding relation and object distance and the relation of definition with object distance, the definition correspondence corresponding to Fig. 4
Field depth 2000mm ± 8mm of the virtual image away from as virtual test camera 10, realize the virtual image by the module 100 away from distribution
Concentrate in the range of 2000mm ± 8mm, meet design the virtual image away from the requirement for 2m, realize the virtual image to the module 100 away from
Calibration.In the present embodiment, internal thread and external screw thread 22-1 ridge rotate eyeglass module 20 away from can be set to 0.28mm
Angle can correspond to the object distance for adjusting 0.02mm when being 30 °, can meet actual use.
The wear-type product optics module 100 of the present embodiment, first by the virtual image away from test camera 10 focus the virtual image away from,
When eyeglass module 20 rotates relative to screen module 30, the definition of the virtual image, realization pair are observed in the virtual image is away from test camera 10
The virtual image of the optics module 100 away from calibration, realize the virtual image between eyeglass 21 and screen 31 away from unification, improve user pendant
Wear the perception experience during wear-type product with the optics module 100.
Finally it should be noted that：Above example is only to illustrate the technical solution of the utility model, rather than its limitations；
Although the utility model is described in detail with reference to the foregoing embodiments, it will be understood by those within the art that：
