Containing in the inner.If in step 1317 is contained in, then step 1301 then will not be contained in it.Selectable at each
In step 1301 and 1317, a selectable lens arra is made on one second side of this substrate.In step 1301 and
In an example in 1317, lens 408 are made on one second side of substrate 406.That is, if be included, lens 408
Can manufacture on one second side of substrate 406 before or after manufacturing achromatism biprism array 102.
In the example of Fig. 1 to 15, owing to sub-camera 306 (5) need not revise the visual field of its correspondence, therefore the first prism
402 are not included in it.In other words, it is assumed that camera 100 is to be formed by N x N camera 306 array of a symmetry, when
When N is odd number, the central achromatism biprism of this achromatism biprism array 102 can not comprise the first prism 402 but can comprise
Material corresponding to other the second prisms.When N is even number, this central sub-camera selectively comprises one first prism.Example
As, in 4x 4 array, four sub-cameras at camera 100 center can only comprise the second material.Or, a 4x 4 gusts
In row, four parts at center can comprise first and second both prism.Figure 16 is that explanation one has the method by Figure 13
The generalized section of the exemplary camera 1600 of the 2x 2 achromatism biprism array 1602 that 1300 are formed.Camera 1600
There is achromatism biprism array 1602, lens arra 1614 and a sensor array 1616.In the example of Figure 16, take the photograph
Shadow machine 1600 is formed as a 2x 2 sub-camera array, and thus not there is middle center camera, the sub-camera of each of which
Comprise first and second both prism 1604,1606.
As shown in Figure 15 A-C, formation the can be made from a single material layer that adjoins encapsulating each the first prism 402
Second material of two prisms 404.Advantageously, the second prism 404 and time of the first prism 402 of alignment is which saved.Favorably
, the second mould 1508 can be configured and makes the upper surface of the only first prism 402 by the second of the second prism 404 out of the ordinary
Material covers with the method being similar to Fig. 3 and 4.Advantageously, the material used forming the second prism array is which saved
Material consumption expense.
Without departing from scope when, said method and system can be made a change.Therefore should be understood that
It is that described above or the content being shown in accompanying drawing should be interpreted that illustrative sense and nonrestrictive meaning.Following application
The scope of the claims is intended to all general features as herein described and special characteristic, and due to the relation of language, this method and
The statement of the category of system all should fall into therebetween.
