Abstract
The invention discloses a reflector. The reflector comprises a panel body and a plurality of semi-spherical grooves uniformly formed in the surface of the panel body. Due to the fact that the spherical grooves are used for diffuse reflection, the reflectivity is high relative to normal diffusion reflection, light uniformity is maintained, and the reflector is easier for camera matrix arrangement relative to a spherical integral lamp source.
Description
Technical field
The present invention relates to a kind of reflector for detecting of diffuse-reflectance apparatus field.
Background technology
Current existing reflector generally employ the mode arranging fine sand on panel, in the detection in order to ensure the even of light, usually adopts ball integration lamp source. But still cannot meet the needs of high precision test.
Summary of the invention
It is an object of the invention to provide a kind of reflectivity height, the reflection uniform reflector of light.
For achieving the above object, the technical solution used in the present invention is:
A kind of reflector, comprises the groove that panel body is spherical with the multiple semicircles being evenly distributed on described panel body surface.
Preferably, described panel body is diffuse reflector.
Preferably, described groove inwall is provided with reflecting coating.
Further preferably, described reflecting coating is refletorized paint layer.
Preferably, the diameter of described groove is 1mm, and described groove is arranged with many rows in parallel, and the centreline spacings of adjacent two rows are 5mm, and the distance between the center of adjacent two grooves often arranged is 5mm, often arranges toward its same length direction 3mm that staggers between adjacent two rows.
A kind of detection device, it comprise the rectangle being positioned at bottom base plate, four connect with four limits of described base plate respectively and the light source arranged along described base plate four edges portion respectively of vertically disposed reflector, four strips and the lid tinted shade that is located on described reflector, being provided with circular through hole in the middle part of described tinted shade 6, the top of described reflector is above-mentioned reflector.
Preferably, the direct projection light of described light source and the angle of described reflector are 5 ��.
Preferably, upper part of described reflector is described reflector, and lower part is coated with refletorized paint layer.
Preferably, described tinted shade is black light-absorbing sheet material.
Preferably, described base plate is square.
Owing to technique scheme is used, the present invention compared with prior art has following advantage:
Carry out diffuse-reflectance owing to present invention employs ball recess, relative to common diffuse-reflectance, reflectivity height, maintain light homogeneity, and be more easy to the arrangement of camera matrix relative to ball integration lamp source.

In above accompanying drawing: 1, body; 2, groove; 3, base plate; 4, reflector; 5, light source; 6, tinted shade; 7, fine sand.
Embodiment
Below in conjunction with embodiment shown in the drawings, the invention will be further described:
Shown in FIGS 1-2, a kind of reflector, comprises the groove 2 that panel body 1 is spherical with the multiple semicircles being evenly distributed on panel body 1 surface. Panel body 1 is diffuse reflector, and groove 2 inwall is provided with refletorized paint layer.
Accompanying drawing 3 is existing reflector cross section partial enlargement schematic diagram, panel is arranged reflective fine sand 7 and become, arrow in figure represents radiation direction, relatively can increase by the reflection light of about 20% inject the reflector of rear the present embodiment according to test light after with existing reflector.
As shown in Figure 2, the diameter of groove 2 is 1mm, and groove 2 is arranged with many rows in parallel, and the distance a between the center of adjacent two grooves 2 often arranged is 5mm, the centreline spacing b of adjacent two rows are 5mm, often between adjacent two rows toward its same length direction distance c that staggers be 3mm. Light after the reflection of this arrangement mode can be easy to the arrangement of camera matrix.
Shown in FIGS 4-6, a kind of detection device, it base plate 3, four comprising the square being positioned at bottom connects with four limits of base plate 3 and the tinted shade 6 being located on reflector 4 along light source 5 and the lid of the setting of base plate four edges portion respectively of vertically disposed reflector 4, four strips respectively, this tinted shade 6 is black light-absorbing sheet material, circular through hole is left in the middle part of it, by this through hole, camera lens can collect the test specimen pattern in the middle part of detection device tank-top plate, and the top of reflector is above-mentioned reflector. The direct projection light of light source 5 and the angle of reflector 4 are 5 ��. Upper part of reflector is reflector, and lower part surface is coated with refletorized paint layer.
The middle part that sample is placed on base plate 3 when detecting, adopts camera in the collection carrying out image on tinted shade 6 top. Carry out diffuse-reflectance owing to the present embodiment have employed ball recess, relative to common diffuse-reflectance, reflectivity height, maintain light homogeneity, and be more easy to the arrangement of camera matrix relative to ball integration lamp source.
Above-described embodiment, only for the technical conceive of the present invention and feature are described, its object is to allow person skilled in the art can understand the content of the present invention and implement according to this, can not limit the scope of the invention with this. All equivalences done according to spirit of the invention change or modify, and all should be encompassed within protection scope of the present invention.
