Embodiment 1
Referring to Fig.1-6, the first embodiment of the present invention:
For existing microwell array structure and solid light micro channel array structure because logical using this non-inclined of direct light channel
Problem brought by road, the invention proposes a kind of solid light micro channel array panel with ramp way.Such as Fig. 1 and 2 institute
Show, which mainly includes opaque matrix 1 and multiple light transmission passages 2.
Wherein, light transmission passage 2 use transparent optical medium (such as transparent glass, transparent plastic, optical fiber, filter glass,
Filtering plastics etc.) it is used as optical channel, play the role of that light is allowed to pass through.In addition, light transmission passage 2 is solid optical channel.
Opaque matrix 1 uses opaque or extinction material (such as jealous glass, opaque plastics) conduct
Spacer plays the role of the light being isolated between each light transmission passage 2.
As depicted in figs. 1 and 2, opaque matrix 1 is filled between each light transmission passage 2.
For the light transmission rate for promoting channel, the present invention can also substitute single transparent medium using optical fiber structure to make
Optical channel array, as shown in Figure 3.In Fig. 3,1 is opaque matrix, and 21 be fiber core layer, and 22 be fibre cladding.
The shape of the cross section of light transmission passage 2 can be circle or rectangular, and solid light micro channel array panel is transversal
There are many various arrangements modes such as square arrangement, rounded projections arranged for each light transmission passage 2 in face.It is real therefore from the point of view of cross section
The shape and arrangement mode of heart light micro channel array panel can for circular channel square arrangement, circular channel rounded projections arranged,
Square duct square arrangement and square duct rounded projections arranged etc., as shown in Fig. 3, Fig. 4, Fig. 5 and Fig. 6.
To realize that better image quality, the present invention can also according to certain rules replace partially transparent optical channel
At opaque or extinction material, thus the utility model has the advantages that first is that the veiling glare absorbability of enhancing product, is promoted of both playing
The contrast and clarity of image；Second is that changing the array angle and period frequency of optical channel by the method for this partial replacement
Characteristic, to mitigate the Moire fringe defect generated when the imaging sensors such as product of the present invention and CCD or CMOS couple.Fig. 8
A kind of specific alternative is given, is laterally or longitudinally just substituted for a light transmission passage every 4 light transmission passages impermeable
Optical element 3.The rule of replacement can also be other implementations, as long as partial light permeability channel is substituted for impermeable optical element i.e.
It can.
