Passing through for certain coloured light also just changes.For example beam of white light, by blue color filter, injection is a branch of blue light, and green
Light, feux rouges are few, most of to be absorbed by optical filter.Correspondingly, it is appreciated that Red lightscreening plate can only allow feux rouges to pass through, it is green
Colo(u)r filter can only allow green light to pass through, and so on.The color of optical filter 112 and two parallel colour bands in target image
Color is corresponding, i.e., if the color of two parallel colour bands is respectively red and green, optical filter 112 includes a red filter
Piece and a green color filter, wherein it is that red parallel colour band is logical that Red lightscreening plate, which can only allow color in two parallel colour bands,
It crosses, it is that green parallel colour band passes through that green color filter, which can only allow color in two parallel colour bands,.It is understood that optical filter
112 number is equal with the number of parallel colour band, since optical filter 112 is placed at micropore, the number of optical filter 112
It is equal with the number of micropore.Since the number of parallel colour band is two, the number of optical filter 112 is also two, micropore
Number be also two.In addition, two micropores are also parallel.Meanwhile micropore to open up direction parallel with colour band, i.e., if two are micro-
Hole is parallel in the vertical direction, then two colour bands are also parallel in the vertical direction；If two micropores are parallel in the horizontal direction,
Then two colour bands are also parallel in the horizontal direction.Specific micropore opens up direction and can be set according to the actual situation, herein not
Make specific limit.
Optionally, based on the above technical solution, processor 12 is according to target spacing, concavees lens 111 and sheet glass
The pantograph ratio of the spacing and concavees lens 111 between spacing, micropore between 113 determines the eyesight value of tested user.
In an embodiment of the present invention, as shown in Fig. 1 n, the eyesight value Computing Principle signal of Vission detector is given
Figure.T is focus, when being tested user visually two parallel colour bands coincidences, is imaged on the retina of tested user anti-
Direction extended line is formed by.B is the spacing between two micropores, and a is concavees lens 111 (i.e. detection concavees lens) and sheet glass
Spacing between 113, b are imaging size, and X is target spacing, if the pantograph ratio of concavees lens 111 is ε, then b=ε X.It needs to illustrate
, after Vission detector determines, the spacing B between spacing a, two micropores between concavees lens 111 and sheet glass 113
Pantograph ratio ε with concavees lens 111 is just definite value, and on this basis, if getting target spacing X, size b is imaged can
It is determined according to formula b=ε X.
According to formulaCalculate eyesight value, wherein D is eyesight value, and f is focal length, is now needed according to the mesh got
Mark spacing X determines focal length f, that is, establishes the mathematical model of target spacing X Yu focal length f, in order to establish the mathematical model, introduce coke
Away from Equivalent Thought, i.e., for being tested for user, in time eyesight detection process, eyesight value D is definite value, in other words,
For tested user, in time eyesight detection process, the focal length f got is definite value.That is, focal length f and concavees lens
The position of 111 (i.e. detection concavees lens) is unrelated.There is following processing mode based on above-mentioned: firstly, it is necessary to explanation, eyesight inspection
Correction concavees lens are surveyed in device and do not included, detection concavees lens (i.e. concavees lens 111) is only included, introduce correction concavees lens here only
It is to better understand focal length f.Focal length f is the metric form that focusing or the diverging of light are measured in optical system, refers to directional light
The distance between the focus assembled from optical center of lens to light when incident.In simple terms, focal length f is focal point to the central point of face mirror
The distance between.
