Abstract
The utility model provides a special linear source to improve the imaging quality in criminal investigation trace expertise, which belongs to criminal investigation trace expertise tools. The utility model comprises a source position adjusting rack and a linear source which is arranged on the source position adjusting rack. Compared with the prior art, the special linear source to improve the imaging quality in criminal investigation trace expertise of the utility model has the advantages of reasonable design, simple structure, convenient usage, imaging quality improvement and imaging stability, etc, therefore the utility model has high value of market popularization and application.
Description
1, technical field
The utility model relates to a kind of criminal investigation vestige Identification Tools, and specifically a kind of criminal investigation vestige that improves image quality is identified the industrial siding light source.
2, technical background
The criminal investigation vestige is identified the sample that normally several is had the feature vestige, and analysis determines whether to belong to same main body and does.Have in the criminal investigation vestige much to belong to linear vestige such as pincers and cut vestige, wipe the rifling vestige of cut mark and bullet etc., it is identified generally use directed point source of light to manifest indication character as light fixture.Point source of light has two significant disadvantages: regulate difficulty and illumination and be difficult to realize standardization.
Point source of light belongs to directional light, its radiation direction is very big for the imaging effect influence of vestige, in order to obtain desirable mark image, need carefully to regulate repeatedly, because three-dimensional direction has two degree of freedom, its adjusting workload is big, in case change sample or microscopical enlargement factor, mobile device etc., need readjust the direction of light source.
Different samples require the illumination direction of light source identical when identifying, both mark images just have comparability like this, illumination direction deviation size directly influences qualification result, but because the relation between linear vestige direction and pointolite direction is difficult to quantitatively determine, thereby the lighting condition of the mark image of two samples is difficult to accomplish identical, just is difficult to realize the standardization of vestige illumination.
3, summary of the invention
The purpose of this utility model is at above weak point, provides a kind of simple in structure, imaging stable, regulates the criminal investigation vestige that improves image quality simply and easily and identifies the industrial siding light source.
The technical scheme that its technical matters that solves the utility model adopts is: line source is arranged on the light source position adjusting bracket.During use, only need adjust the light source position adjusting bracket a little and just can obtain high-quality imaging.
The criminal investigation vestige of raising image quality of the present utility model identifies that the industrial siding light source compares with prior art, has and regulates easily, and the characteristics of indication character good developing effect, thus also accomplish the standardization of the identical realization of the lighting condition vestige illumination of two samples easily.The joint problem of withering that does not have direction, realize the quantification of light source position easily, alleviated the workload of regulating greatly, and imaging is stable, light source position reduces the difference that characteristics of image manifests, because the vestige line orientations is consistent with the line source direction, its vestige manifests image effect and obviously is better than spot light.
4, description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing 1 is identified the structural representation of industrial siding light source for the criminal investigation vestige that improves image quality;
Accompanying drawing 2 is the vertical view of Fig. 1.
5, embodiment
With reference to Figure of description the criminal investigation vestige of raising image quality of the present utility model is identified that the industrial siding light source explains below doing.
The criminal investigation vestige of raising image quality of the present utility model is identified the industrial siding light source, and its structure is to be made of light source position adjusting bracket 1 and line source 2, and light source position adjusting bracket 1 is provided with line source 2.
The criminal investigation vestige of raising image quality of the present utility model identifies that its processing and fabricating of industrial siding light source is very simple and convenient, and processing and fabricating gets final product shown in the by specification accompanying drawing.
Except that the described technical characterictic of instructions, be the known technology of those skilled in the art.
