Abstract
The invention provides a kind of method for weakening the annular optical illumination ghost of telecentric optical system, it makes full use of bottom light-source brightness, while preventing the illumination for producing ghost from being mapped to low light source, weakens ghost, improves the rate of precision of measurement and detection.It includes glass objective table, telecentric lens are disposed with above the glass objective table, the outer ring surface of the telecentric lens is disposed with annular light source, the annular light source is pointed into the object on the glass objective table, the arranged beneath of the glass objective table has telecentric lightses, the telecentric lightses are pointed into the object on the glass objective table, it is characterised in that：Filter part is placed between glass objective table and telecentric lightses, the filter part possesses very high to telecentric lightses transmitance while the characteristics of ending most of ring light.
Description
Technical field
It is specially that a kind of telecentric optical system ring light that weakens shines the present invention relates to radiographic measurement and the technical field of detection
The method of bright ghost.
Background technology
Telecentric system includes telecentric lens+telecentric lightses composition, and telecentric lens and telecentric lightses are usually by lens design
Teacher is separately designed, and heart system configuration ring light too far or the intense ambient near from center of circle systematic comparison are not almost accounted in design
The influence that light is produced in telecentric system, even if considering this factor in design, not only brings great difficulty to design and is difficult
Accomplish to be completely eliminated；There is such ghost in current telecentric system.The generation of ghost mainly due to annular optical illumination or
The light that relatively near extraneous illuminator is sent interreflection between telecentric lightses and telecentric lens is caused.The presence of ghost removes shadow
Outside sound observation area is attractive in appearance, very big interference can be caused to measurement and detection.
The content of the invention
In view of the above-mentioned problems, the invention provides a kind of method for weakening the annular optical illumination ghost of telecentric optical system, its
Bottom light-source brightness is made full use of, while preventing the illumination for producing ghost from being mapped to low light source, weakens ghost, measurement is improved and detects
Rate of precision.
A kind of method for weakening the annular optical illumination ghost of telecentric optical system, its technical scheme is such, and it includes glass
Telecentric lens are disposed with above glass objective table, the glass objective table, the outer ring surface of the telecentric lens is disposed with ring light
Source, the annular light source is pointed into the object on the glass objective table, and the arranged beneath of the glass objective table has telecentric lightses,
The telecentric lightses are pointed into the object on the glass objective table, it is characterised in that：By filter part be placed in glass objective table and
Between telecentric lightses, the filter part possesses very high to telecentric lightses transmitance while can end the spy of most of ring light
Point.
It is further characterized by：
The filter part is directly mounted at the light source end of the telecentric lightses；
It is described optical filtering broadcast between be specially flat board coloured glass or optical filter.
After the present invention, because filter part is placed between glass objective table and telecentric lightses, the filter part tool
For very high to telecentric lightses transmitance while the characteristics of ending most of ring light, filter part is by putting down that telecentric lightses are sent
Row fairing profit reaches glass objective table, but intercepts quite a few illumination sent from annular light source simultaneously and be mapped to telecentric lightses,
It makes full use of bottom light-source brightness, while preventing the illumination for producing ghost from being mapped to low light source, weakens ghost, improves measurement and examines
The rate of precision of survey.
Brief description of the drawings
Fig. 1 is the telecentric system schematic diagram for adding filter part；
Fig. 2 is not plus filter part surveys ghost figure；
Fig. 3 is the improved ghost figure after addition green glass；
Figure is that the title corresponding to middle sequence number is as follows：
Glass objective table 1, telecentric lens 2, annular light source 3, object 4, telecentric lightses 5, filter part 6.
Embodiment
A kind of method for weakening the annular optical illumination ghost of telecentric optical system, is shown in Fig. 1, it includes glass objective table 1, glass
The top of objective table 1 is disposed with telecentric lens 2, and the outer ring surface of telecentric lens 2 is disposed with annular light source 3, and annular light source 3 is pointed into glass
Object 4 on glass objective table 1, the arranged beneath of glass objective table 1 has telecentric lightses 5, and telecentric lightses 5 are pointed into glass objective table 1
On object 4, filter part 6 is placed between glass objective table 1 and telecentric lightses, filter part 6 possesses saturating to telecentric lightses 2
Cross rate very high while the characteristics of most of ring light can be ended, the coloured glass or optical filter of the specially flat board of filter part 6.
In specific embodiment, filter part 6 is directly mounted at the light source end of telecentric lightses 3.
Specific embodiment, is shown in Fig. 1~Fig. 3：Telecentric lightses 3 are green LEDs, and annular light source 3 is White LED, do not add and filter
Ghost is surveyed after part, Fig. 2 is seen；Green glass is installed on the light source end of telecentric lightses 3, i.e. low light source as filter part 6
End is loaded onto after green glass, and the ghost after improvement is shown in Fig. 3；It makes full use of bottom light-source brightness, while preventing to produce ghost
Illumination is mapped to low light source, weakens ghost, improves the rate of precision of measurement and detection.
The specific embodiment of the present invention is described in detail above, but content is only the preferable implementation of the invention
Example, it is impossible to be considered as the practical range for limiting the invention.All impartial changes made according to the invention application range
Change and improvement etc., all should still be belonged within this patent covering scope.
