Abstract
The utility model discloses a colony and inhibition zone dark background imaging system comprising a dark background chamber, a culture dish, an upper secondary light source and an image collector. The four portions are arranged in a same axis and are arranged on a special fixed frame. The inner wall of the dark background chamber is of a cone shape and a light source is fixed on the inner wall. The ray emitted from the light source on the inner wall is capable of directly irradiating on the floor of the culture dish through a glass support of the culture dish, and the ray emitted from the upper secondary light source directly irradiates on the surface of the culture dish. The image collector is capable of simultaneously receiving reflected light, refracted light and diffuse light which are from the culture dish. The utility model is capable of being used to observe and analyze microorganism in the fields such as a biology field and a medicine field, and has the advantages of compact structure and ingenious modeling.
Description
Technical field
The utility model relates to optics and digital imagery field, relates in particular to a kind of bacterium colony and inhibition zone dark background imaging system.
Technical background
Formerly in the technology, imaging for bacterium colony and inhibition zone, what most imaging system adopted is the method for top light source, and the method existence of top light source is observed difficult problem to tiny bacterium colony and deep colony, also bad differentiation border when approaching for the bacterium layer that forms inhibition zone.The method that adopts backlight is also arranged, but light source for light source color near or the approaching bacterium colony of nutrient culture media color and the bacterium colony of paler colour also be not easy to differentiate.Formerly all exist not enough in the technology: 1) bacterium colony and inhibition zone imaging are subjected to the influence of sample, have limitation; 2) the light distribution inequality on the sample, one-tenth image distortion cause the observations deviation bigger.
The utility model content
The purpose of this utility model is to address the above problem, and a kind of bacterium colony and inhibition zone dark background imaging system are provided.
Technical solution of the present utility model is as follows:
A kind of bacterium colony and inhibition zone dark background imaging system, it is characterized in that, comprise this four part of dark background chamber, double dish, top secondary light source and image acquisition device, to going up coaxial cable and arrange down, all parts are installed on the special fixed mount this four part successively, wherein, described dark background chamber is made up of inwall, light source, glass supporter, base plate, and described inwall is cone shape, and light source is fixed on the inwall, glass supporter is fixed on the inwall upper surface, and the inwall baseplane seals with base plate.
Light source on the described inwall is positioned at the oblique below of double dish, distributes ringwise.
Described top secondary light source is positioned at the oblique upper of double dish, distributes ringwise.
Described image acquisition device be positioned at the double dish axis directly over.
The utility model has following advantage with respect to technology formerly:
1) light distribution is even, not influenced by external light source, and imaging is undistorted.
2) the double dish specification is unrestricted, and nutrient culture media is chosen freer.
3) imaging of bacterium colony and inhibition zone is clear, reduces its true appearance accurately.
4) compact conformation, structure is exquisite.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a dark background cell structure synoptic diagram of the present utility model.
Fig. 3 is specific embodiment synoptic diagram of the utility model.
Embodiment:
Describe the utility model in detail with embodiment with reference to the accompanying drawings below.
As illustrated in fig. 1 and 2, a kind of bacterium colony and inhibition zone dark background imaging system, comprise dark background chamber 101, double dish 102, top secondary light source 104 and image acquisition device 105 these four parts, this four part is successively to going up coaxial cable and arrange down, all parts are installed on the special fixed mount 103, wherein, dark background chamber 101 is made up of inwall 201, light source 202, glass supporter 203, base plate 204.Inwall 201 is cone shape, and light source 202 is fixed on the inwall 201, and glass supporter 203 is fixed on the upper surface of inwall 201, and the inwall baseplane seals with base plate 204.Light source (202) on the inwall (201) is positioned at the oblique below of double dish (102), distributes ringwise.Top secondary light source (104) is positioned at the oblique upper of double dish (102), distributes ringwise.Image acquisition device (105) be positioned at double dish (102) axis directly over.Inwall 201 and base plate 204 whole painted blacks are avoided the light reflection.
As shown in Figure 3, a specific embodiment of a kind of bacterium colony and inhibition zone dark background imaging system.Light source 202 adopts the light source with certain dispersion angle, the light O that light source 202 is sent
1 Glass supporter 203 by double dish 102 can direct irradiation on double dish 102 bottoms because the nutrient culture media in the double dish is transparent or semitransparent, light O
1Can directly see through nutrient culture media, if grown bacterium colony and bacterium layer in nutrient culture media, these bacterium colonies and bacterium layer will produce refraction, reflection or diffuse reflection to light, and part refraction, irreflexive light enter into image acquisition device 105 and forms image.In imaging, because base plate 204 all sprays into black and can not produce reflection, so the wide part of collecting in the collector 105 comes from refraction, irreflexive light of bacterium colony and the generation of bacterium layer, at this moment the image of bacterium colony and bacterium layer will be very clear, to reach the purpose of observing imaging.
When posting marker such as tablet when double dish 102 upper surfaces, because these markers are opaque, image acquisition device 105 may be unclear to these marker imagings, at this moment, and the light O that top secondary light source 104 is sent
4The meeting direct irradiation is on these markers, and reflection back light enters into image acquisition device 105, will obtain an imaging clearly like this.
The foregoing description is to be used for explaining the utility model, rather than the utility model is limited, and in the protection domain of the utility model claim, any modification and change for the utility model is done all fall into protection domain of the present utility model.
