A kind of test surfaces device for the test of flake module
Technical field
This utility model relates to the test of flake module, particularly to a kind of test surfaces device for the test of flake module.
Background technology
The evaluation and test of current industry build-in test flake Radix Rumicis class module, is all based on plane test;Owing to the angle of visual field of flake module is big, distorting big, the mode of plane test because the existence of the depth of field and aberration problems, can cause the image effect of the result tested out and actual flake module there are differences;Simultaneously as the angle of visual field is big, the space that plane test takies is big.
Utility model content
For above-mentioned deficiency, the purpose of this utility model is in that, a kind of test surfaces device for the test of flake module is provided, various point locations distance is all consistent to test surfaces to realize flake module, thus avoiding the difference of the module depth of field and distortion, it is also possible to avoid the problem that the required test space that causes greatly because of the angle of visual field in plane test is big.
The technical solution adopted in the utility model is: a kind of test surfaces device for the test of flake module, including flake module and the test surfaces that is correspondingly arranged with flake module, it is characterized in that, described test surfaces is spherical testing curved surface, described flake module is arranged at the sphere center position of spherical testing curved surface, and makes each visual field of flake module all consistent to the distance of spherical testing curved surface.
Further, described spherical testing curved surface is little hemisphere, hemisphere or hemispherical curved surface.The angle of flake module and measuring distance according to required test define.The centre of sphere can need by actual flake module or customer requirement definition to the distance (i.e. radius of sphericity) of spherical testing curved surface.
Further, each point on described spherical testing curved surface is equal to the distance of flake module.
Further, the skeleton of described spherical testing curved surface is formed by some warps and some parallels are staggered.Described warp and parallel are four.
Further, the inner side of described spherical testing curved surface is test surface layer, and outside is light shield layer.
Further, described light shield layer is the shade of black.
This utility model has the advantage that and realizes flake module various point locations distance is all consistent to test surfaces, thus the test result difference avoiding flake module to cause because of the depth of field and aberration problems, tests out the image effect of flake module more accurately;It is also possible to avoid the problem that the required test space that causes greatly because of the angle of visual field in plane test is big.Longitude and latitude skeleton is crisscross to be formed, and bulk strength is good, and can pass through elastic deformation and immediately finely tune, more excellent than integrated sphere curved surface.
Illustrating below in conjunction with accompanying drawing and detailed description of the invention, the utility model is described in further detail.

Detailed description of the invention
Referring to Fig. 1 to 2, test surfaces device for the test of flake module provided by the utility model, including flake module 1 and the test surfaces that is correspondingly arranged with flake module 1, described test surfaces is spherical testing curved surface 2, described flake module 1 is arranged at the sphere center position of spherical testing curved surface 2, and makes each visual field of flake module 1 to the distance all consistent (being embodied in each point on described spherical testing curved surface equal to the distance of flake module) of spherical testing curved surface 2.
Specifically, described spherical testing curved surface 2 is hemisphere curved surface.The angle of flake module and measuring distance according to required test define.The centre of sphere can need by actual flake module or customer requirement definition to the distance (i.e. radius of sphericity) of spherical testing curved surface.
Specifically, by some warps 3 and some parallels 4 are staggered forms for the skeleton of described spherical testing curved surface 2.Described warp 3 and parallel 4 are four.Longitude and latitude skeleton is crisscross to be formed, and bulk strength is good, and can pass through elastic deformation and immediately finely tune, more excellent than integrated sphere curved surface.
Specifically, the inner side of described spherical testing curved surface 2 is test surface layer, and outside is light shield layer.Described light shield layer is the shade of black.
This utility model is not limited to above-mentioned embodiment, adopts the technical characteristic identical or approximate with this utility model above-described embodiment, and other obtaining are for test surfaces devices of flake module test, all within protection domain of the present utility model.
