Description
Technical field
The invention belongs to photo illumination technical field, relating to a kind of for thoroughly eliminating the reflective photographic illumination apparatus of dental surface.
Background technology
Reflective in photography is ubiquitous, is divided into the reflective and non-specular surface reflecting of minute surface.The reflective surface being present in smooth object of minute surface, often other highlighted object reflections on shot object in light source or environment.The factor that non-specular surface reflecting is formed is then more complicated, and under natural daylight condition and under not using the prerequisite of filter, non-specular surface reflecting is ubiquity and cannot thoroughly eliminates.Polarization filter can be used to weaken at product and landscape photography field photographer or eliminate the non-specular surface reflecting on the shooting body, but the minute surface that traditional using method of polarization filter cannot eliminate light source is reflective.
Dentistry particularly prosthetics specialist needs to link up colouring information by photo and artificial tooth technician and/or patient.The enamel on natural teeth surface can show mirror-reflection and non-mirror reflection in shooting simultaneously, and two kinds reflect the judgement that all can have influence on dentine color.The personalized morphosis such as dentine grows leaf in addition, finger-like is dashed forward can show better after removal enamel is reflective, are convenient to technician and imitate and copy.
Present most of dentist also cannot take reflective by the tooth photo thoroughly eliminated, and sub-fraction dentist modifies annex by the light source added in traditional microspur flash lamp front and obtains above-mentioned effect.First the shortcoming of this mode is need to configure traditional microspur flash lamp, along with the development of aesthstic dentistry has generally admitted the needs that this quasi-tradition microspur flash light source can not meet aesthstic dental photography now.Secondly there is technique sensitive in the installation process of this type of light source modification annex, the reflective elimination of picture will be made not thorough more than 3 ° of angular errors.
Summary of the invention
The object of the invention is the deficiency for above-mentioned technology, the accessories apparatus that a kind of thorough elimination dental surface is reflective is provided.

Described light source uses hot shoe flash lamp, and flash head light-emitting area is parallel with hot shoe plane; The light ray parallel that two described light sources send is arranged, and the axial line distance of two light sources is 4 ~ 6cm;
The flat board of described light source modifies auxiliary to be light transmittance be 0 ﹪, flat board has three through holes, and is equipped with polarizing coating in three through holes; Second and third through hole uses same polarizing coating, so the polarization angle in two holes is zero; On first through hole, on polarizing coating and second and third hole, the polarization angle of polarizing coating is 90 °.
The first described through hole, as viewfinder, is positioned at above second and third through hole, and second and third through hole is located at flash lamp lamp holder front respectively, and just to setting;
Second and third described through hole top edge and the distance of first through hole lower limb fully meet the light-emitting area blocking flash lamp lamp holder, and the first lead to the hole site is required to meet as far as possible close to flash lamp lamp holder simultaneously; Actual light-emitting area, position consistency in the size of second and third through hole, position and flash lamp lamp holder.
As preferably, the first through hole is rectangular configuration, and long is 8cm, and wide is 8cm;
As preferably, second and third through hole is rectangular configuration, and long is 4cm, and wide is 1cm.
Beneficial effect of the present invention:
1) the present invention adopts light source and light source modification annex to be all placed on telescoping shoring column, can alleviate gripping weight;
2) in apparatus of the present invention use procedure, patient sits up straight and support is positioned on patient facial region's center line, is conducive to finding symmetric relation;
3) in apparatus of the present invention shooting process, camera can directly be placed on this device axis to guarantee symmetric relation by doctor;
4) camera is placed in and device is also convenient to doctor's one hand takes, and left hand takes shade guide teeth;
5) viewfinder is positioned at and is conducive to doctor above light source and obtains the natural labial teeth of bulging and laugh at line.

Fig. 1 is this device overall schematic, and wherein 1 is telescoping shoring column, and 2 is light source, and 3 is light source modification annex;
Fig. 2 is that light source modifies accessory structure schematic diagram, and wherein 3-1 is the first through hole, and 3-2 is the second through hole, and 3-3 is third through-hole;
Fig. 3 (a) controls to the tooth photo of tooth both sides, the tooth photo that Fig. 3 (b) takes for embodiment of the present invention method for mirror-reflection.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further analyzed.
As shown in Figure 1, apparatus of the present invention comprise telescoping shoring column 1, two is fixed on telescoping shoring column light source 2, light source modification auxiliary 3 by fixture; Light source is modified auxiliary 3 and is positioned at light source 2 flash lamp lamp holder front, and the spacing that light source modifies auxiliary 3 and lamp holder is more than or equal to 0.5mm;
Described light source 2 uses hot shoe flash lamp, and flash head light-emitting area is parallel with hot shoe plane; The light ray parallel that two described light sources 2 send is arranged, and the axial line distance of two light sources 2 is 4-6cm;
As shown in Figure 2, described light source modification auxiliary 3 is the flat board of 0 ﹪ for light transmittance, flat board has three through holes, and is equipped with polarizing coating in three through holes; Second and third through hole 3-2,3-3 use same polarizing coating, so the polarization angle in two holes is zero; On first through hole 3-1, the polarization angle of polarizing coating and the upper polarizing coating of second and third hole 3-2,3-3 is 90 °.
The first described through hole 3-1 is as viewfinder, and be positioned at above second and third through hole 3-2,3-3, second and third through hole 3-2,3-3 are located at flash lamp lamp holder front respectively, and just to setting;
Described second and third through hole 3-2,3-3 top edge and the distance of first through hole 3-1 lower limb fully meet the light-emitting area blocking flash lamp lamp holder, and the first through hole 3-1 status requirement meets as far as possible close to flash lamp lamp holder simultaneously; Actual light-emitting area, position consistency in the size of second and third through hole 3-2,3-3, position and flash lamp lamp holder.
