Description
Technical field
This utility model belongs to technical field of image acquisition, more particularly to one kind is when shooting under visible ray and non-visible light
Can exact focus device.
Background technology
Because all of camera lens has aberration and dispersion, and the wavelength difference of visible ray and non-visible light is larger, so, together
One shooting point, different light are different by the position of lens imaging to target surface (sensor), that is to say, that different light
Imaging surface is misaligned, this position difference in the position of axial direction, and term is through focus value.Such as, many video cameras are on daytime
The black white image shot when can take the photograph and must be apparent from, but not have light to evening is just relatively fuzzyyer.Reason be exactly be in the evening
Shoot under infrared light, and the wavelength (that conventional is 850nm) of infrared light be than the length of visible ray (400nm-650nm), imaging surface and
Caused by visible ray is misaligned.
Improved method adds 1,2 to reduce or correct color typically by the structure design for improving camera lens and in camera lens
Poor eyeglass；Do so can not only greatly increase cost, and, the resolving power of camera lens can be affected, effect is also limited, also,
Simply in not far wavelength band near visible light wave range, (near-infrared of such as below 1000nm etc.) is effective；If in height
Clear out a gathering place conjunction, such as more than 20,000,000 the picture microshot of pixel put again it is several ten times larger carry out details observation, or remote red
Outer lower to shoot, problem just compares and highlights.
There are a kind of IR camera lenses (i.e. infrared lens) on the market, be by changing lens construction and design of material, coming while simultaneous
Turn round and look at visible ray and near-infrared；But being limited in that for this IR camera lenses, can only take into account visible ray and near-infrared, other light
Just dying；Also, this infrared lens can only accomplish compatibility to visible ray and near-infrared, it is impossible to reach and shoot precisely focusing
Degree.

Cross and camera lens is manually adjusted to upper defocused, using through focus value of the camera lens of record under non-visible light as the skew of the lens focusing
Amount, adjusts the axial side-play amount of camera lens to realize the focusing under the non-visible light manually.
Specifically, if the manual focus module is an accurate axial movement console module, the manual focus
Module specifically for：Manually adjust under visible light camera lens adjust to upper defocused, manually camera lens move axially it is certain
Distance so as to realize the focusing under non-visible light, to the defocused shooting image under the non-visible light.
Further, the distance that the camera lens is moved axially is the camera lens relative under the non-visible light of visible ray
Through focus value.
If the manual focus module be one can manual rotation objective carrier, the manual focus module specifically uses
In：Camera lens is manually adjusted under visible light to upper defocused, is made with through focus value of the camera lens of record under the non-visible light
For the side-play amount of the lens focusing, the side-play amount of camera lens axial direction is adjusted by rotating the camera lens on objective carrier so as to realize at this
Focusing under non-visible light；
Angle=(through focus value/camera lens pitch) of camera lens × 360 ° need to be rotated.
Such as：Such as the through focus value of the camera lens is+0.02mm, and camera lens pitch (conventional) is 0.5mm.Then need to rotate camera lens
Angle is approximate=and+14 °.
Adjust above by the anglec of rotation camera lens axial offset (using simple fixture can just realize 1 °, 2 ° it is smart
The rotation of degree, rotates 7 ° of angles and can just realize high-precision axial movement in 0.01mm), so as to arrange the side of camera lens through focus value
Formula, it is possible to achieve it is accurate right under non-visible light so as to realize that fine setting axial offset is reached by the way of manual rotation
It is burnt.
Further, it is described under visible ray and non-visible light shoot when can exact focus device also include focusing mould
Block controller, if the Focusing module 2 be electromotive focusing module, automatic focusing module or make by oneself in special Focusing module one
Kind, then the through focus value logging modle 1 specifically for：The camera lens of record test in advance is relative under the non-visible light of visible ray
Through focus value is in Focusing module controller；
Specifically, the non-visible light includes near-infrared, mid-infrared, far infrared, ultraviolet, deep ultraviolet etc., if desired at certain
Shoot under kind of non-visible light, then by by the corresponding control button of the non-visible light starting the Focusing module controller, institute
Through focus value under the non-visible light for stating Focusing module controller to be stored in as the camera lens focus under the non-visible light it is inclined
Shifting amount.
If the Focusing module 2 be electromotive focusing module, the electromotive focusing module specifically for：Lead under visible light
Cross manually by button camera lens being adjusted to upper defocused, adjust the skew of lens focusing by starting the Focusing module controller
Measure so as to realize the focusing under the non-visible light.
If the Focusing module 2 be automatic focusing module, the automatic focusing module specifically for：Under visible light certainly
Move to upper defocused, it is non-visible at this so as to realize to adjust the side-play amount of lens focusing by starting the Focusing module controller
Focusing under light.
If the Focusing module 2 is self-control special electric Focusing module, the self-control special electric Focusing module includes one
Individual accurate electronic mobile platform module, the camera lens are fixed in the electronic mobile platform module；Then the self-control is special
Electromotive focusing module specifically for：Camera lens is adjusted under visible light to upper defocused, by starting the Focusing module controller, is come
The axial movement of the electronic mobile platform module is controlled the side-play amount of lens focusing is adjusted so as to realize in the non-visible light
Under focusing.
Above-mentioned self-control special electric Focusing module, using Focusing module controller by the axial movement of control platform reaching
To accurate focusing, the focusing precision higher than common electric Focusing module can be obtained, and is gone for almost all of solid
Horizontal glass head, manual zoom camera lens, motorized zoom lenses and automatic diaphragm lens etc..
It should be clear that：Various light sources scene --- the ultraviolet and infrared scape for having many kinds, different distance being shot
Thing --- microspur, middle-range, long distance camera lens through focus value it is all variant, the through focus value under large aperture and little aperture be likely to difference compared with
Big, etc., under the use environment of various dimensions, the through focus value of a camera lens may up to tens；Therefore, the out of focus of camera lens
Value can be managed in the form of form or data base, and Focusing module controller is again in the form of form or data base calling
And process.
