Ground describes, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.Based on this
The embodiment of invention, every other implementation obtained by those of ordinary skill in the art without making creative efforts
Example, belongs to protection scope of the present invention.
The embodiment of the present invention provides a kind of high-throughput color night vision image instrument, and which employs multiplexing multispectral imaging skills
Art, improves the transmitance for the Baeyer optical filter that conventional color detector uses, and colour information is obtained by decoded mode.
It is a kind of schematic diagram of high-throughput color night vision image instrument as shown in Figure 1, includes mainly：The imaging set gradually
Camera lens, filter set and low-light (level) detector；In Fig. 1,1- imaging lens, 2- filter sets, 3- low-light (level) detectors；
Each filter unit is to be pre-designed through filter in filter set, can penetrate the light of multiple wave bands,
The transmitance of different filter units is interrelated；Filter set is coupled to low-light (level) detector surface, makes each optical filter
Unit is identical as single pixel size, coordinates imaging lens, realizes color night vision image imaging.
In the embodiment of the present invention, the filter set is filter arrays form, and the filter arrays use mosaic
Formula arrangement mode or straight strip type arrangement mode.
In the embodiment of the present invention, the light (RGB+NIR of 3 or 4 wave bands can be used：RGB+infrared).Assuming that being directed to
The light of 4 wave bands, i.e. red, green, blue and infrared band, this 4 wave bands are denoted as 1,2,3,4 successively；
Shown in Fig. 2 a, according to mosaic arrangement mode, and filter arrays are 4 × 5 forms, then 5 filters of the first row
The transmission filter section of filter unit is followed successively by 1+2+3,1+3+4,1+2+3,1+3+4,1+2+3；Second filter unit of row 5
It is followed successively by 2+3+4,1+2+4,2+3+4,1+2+4,2+3+4 through filter section；The third line is identical as the first row, fourth line and second
Row is identical；
As shown in Figure 2 b, according to straight strip type arrangement mode, and filter arrays are 4 × 4 forms, then each row to the 4th
The transmission filter section of row filter unit is followed successively by 1+2+3,1+3+4,2+3+4,1+2+4.
Digital representation single band serial number in Fig. 2, summation indicate that optical filter can penetrate the light of these wave bands.Use this
The luminous flux of color night vision image instrument can be increased by 2 times to 3 times by scheme, and this optical filter is directly coupled to low-light (level) detection
