Description
Technical field
The invention belongs to spectral imaging technology field, relate to visible light separate imaging technology, a kind of three bases
Colo(u)r filter.
Background technology
Optical filter is used to choose the optics of required radiation wave band, is widely used in the optical imageries such as photography, shooting
Equipment.It is generally divided into color filter and two kinds of fundamental types of Thin Film Filter.
Common optical filter is all monochromatic design, and the light that i.e. can only choose a kind of color passes through.But some special should
In with, such as night vision colour imaging instrument, the image co-registration by three kinds of base color of red, green, blue is needed to be processed as true color image, as
Fruit uses conventional monochromatic filter, and operationally complexity is high, and is difficult to meet the demand of fast imaging.
Therefore, it should a kind of multi-color filter of design is to meet above-mentioned particular demands, and quickly can grasp on night vision device
Make.
Summary of the invention
The present invention is to solve existing monochromatic filter deficiency in polychrome demand is applied, it is provided that a kind of three primary colours filter
Mating plate, is mainly used in the equipment such as night vision device, have conversion easy and simple to handle, disclosure satisfy that the advantages such as fast imaging requirement.
The concrete technical scheme of the present invention is, a kind of three primary colours optical filter, and described three primary colours optical filter is circular, including three
Single primary filter of individual sector, the angle of the most each sector is 120.
Further, circular frame is set in the periphery of three primary colours optical filter, simultaneously by the whole disc etc. of circular frame
Be divided into central angle to be 120 degree three parts, dispose red, green, blue list primary filter on every part respectively.
Three primary colours filter center is provided with circular hole.
Three primary colours optical filter can rotate with hands, and motor maybe can be used to drive.
Three kinds of single primary filters are incorporated on a rotating disk, in reality by the three primary colours optical filter of the present invention
In the application of border, it is possible to manually or automatically rotate, meet the fast filtering to three primary colours light and separate.
Compared with prior art, the three primary colours filter sheet structure of the present invention is simple, operation is convenient, has making widely
With being worth and application prospect.
Accompanying drawing explanation
Fig. 1 is the three primary colours optical filter outside drawing of the present invention；
Fig. 2 is the spectral transmittance figure of the three primary colours optical filter of the present invention.
Detailed description of the invention
For the ease of understanding the present invention, in conjunction with accompanying drawing 1-2, the preferred forms of the present invention is described in detail.
Seeing accompanying drawing 1, the three primary colours optical filter outward appearance of the present invention is circular, including three fan-shaped single primary filters,
The angle of the most each sector is 120.
In the present invention, single primary filter uses Febry-Perot (F-P) interferometric filter.Specifically, wherein blue
Optical filter is not more than 2% at wavelength 430-450nm (centre wavelength 435.8nm) scope average reflectance, wavelength 451-simultaneously
760nm average transmittance is not more than 3%；Green color filter is average in the range of wavelength 490-580nm (centre wavelength 546.1nm)
Reflectance is not more than 2%, and in the range of wavelength 430-489nm and 581-760nm, average transmittance is not more than 3% simultaneously；Red
Optical filter average reflectance in the range of wavelength 620-760nm (centre wavelength 700nm) is not more than 2%, simultaneously at wavelength 430-
In the range of 619nm, average transmittance is not more than 3%.
Need when three primary colours light being filtered respectively in applying in view of reality to be switched fast, therefore by three bases of the present invention
Colo(u)r filter is designed to discoid, as arranged circular frame, simultaneously by circular frame in the periphery of circular three primary colours optical filter
Whole disc is divided into three parts that central angle is 120 degree, disposes red, green, blue list primary filter on every part respectively.
By the rotation of disk, the fast filtering to visible ray can be realized, three primary colours light is separated.
In specifically used, circular hole can be set at three primary colours filter center, such that it is able to fixed by three primary colours optical filter
In a rotary shaft, or three primary colours optical filter is set on a fixing axle.Then after light filter, set up CCD
Or cmos camera.When a primary colours region of light filter is before video camera, its imaging can be got by video camera
The monochrome image in region.Manually rotate three primary colours optical filter, gradually obtain tristimulus image.The tristimulus image obtained,
May be used for combined color image.
As the optional means of one, the three primary colours optical filter of the present invention can use motor (such as motor) etc. to drive
Rotate, to replace manual operation.Specifically, when three primary colours optical filter is fixed in a rotary shaft, can be direct with motor
Drive rotary shaft or drive rotary shaft with the use of gear train；When three primary colours optical filter is set on a fixing axle, can
To arrange gear on circular frame periphery, motor mate gear directly three primary colours optical filter is driven.
It is obvious to a person skilled in the art that the invention is not restricted to the details of above-mentioned one exemplary embodiment, Er Qie
In the case of the spirit or essential attributes of the present invention, it is possible to realize the present invention in other specific forms.Therefore, no matter
From the point of view of which point, all should regard embodiment as exemplary, and be nonrestrictive, the scope of the present invention is by appended power
Profit requires rather than described above limits, it is intended that all by fall in the implication of equivalency and scope of claim
Change is included in the present invention.Should not be considered as limiting involved claim by any reference in claim.
Although moreover, it will be appreciated that this specification is been described by according to embodiment, but the most each embodiment only wraps
Containing an independent technical scheme, this narrating mode of description is only that for clarity sake those skilled in the art should
Description can also be formed those skilled in the art through appropriately combined as an entirety, the technical scheme in each embodiment
May be appreciated other embodiments.
