1 is a schematic view schematically showing a speckle inspection apparatus 100 according to an embodiment of the present invention, Figure 2 is an external perspective view showing the speckle inspection apparatus 100 of FIG. 3 is an exploded perspective view illustrating the speckle inspection apparatus 100 of FIG. 1, and FIG. 4 is a cross-sectional view illustrating a cut section of the speckle inspection apparatus 100 of FIG. 1.

First, as shown in FIGS. 1 to 3, the speckle inspection apparatus 100 according to an embodiment of the present invention includes a light source irradiating apparatus 10, a speckle amplifying apparatus 20, and speckle variation detection. Device 30 may be included.

As illustrated in FIG. 4, the light source irradiating apparatus 10 may irradiate the light source L onto the object O. FIG. More specifically, the object O may be in a state in which the internal refractive index is uniform because bacteria or microorganisms are included therein.

In this case, when the light source L emitted from the light source irradiating apparatus 10 is irradiated onto the object O, a very complicated multiple scattering inside the object O is caused by bacteria or microorganisms included in the object O. scattering) may occur. The waves scattered in a complex path through the multi-scattering cause constructive interference or destructive interference with each other, and the constructive or destructive interference of these waves causes a speckle that is a grain pattern. Can be generated. Such a multi-scattering, nano-coating layer (N) or nano-patterning formed in the container 21 of the speckle amplification device 20 to be described later, and other scattering bodies (outer wall of the container 21, plug 22) It may also be generated by the cone projection (51a) formed, the speckle caused by the multi-scattering may be changed according to the movement of the bacteria or the microorganism.

For example, in order to form a speckle by irradiating the light source L to the object O, the light source irradiation apparatus 10 may use a laser beam having a constant wavelength and good coherence. In this case, the shorter the spectral bandwidth of the wave that determines the coherence of the light source L, the greater the measurement accuracy. In this case, the light source irradiating apparatus 10 may include a connector 11 connected to the information communication terminal 31 to receive power from the information communication terminal 31, and receive power through the connector 11.

Accordingly, the light source L having the spectral bandwidth of the wave less than the predetermined reference bandwidth may be used as the light source of the light source irradiating apparatus 10, and the measurement accuracy may increase as the reference bandwidth is shorter than the reference bandwidth. For example, the spectral bandwidth of the light source L can be set to 1 nm or less.

As shown in FIG. 4, the speckle amplification apparatus 20 may amplify a signal of speckle through multiple scattering generated by the light source L irradiated onto the object O. More specifically, the speckle amplification apparatus 20 has an accommodation space in which the object O can be accommodated, and the scattering of the light source L incident therein can be easily performed on the inner surface or the outer surface thereof.

At this time, the bubble prevention device 50 is installed in the speckle amplification device 20 to prevent bubbles from being generated in the object O or the container 21 accommodated in the container 21.

In addition, the container 21 is formed with an incidence portion 21a which is formed transparently on at least a portion of the bottom surface so that the light source L can be incident, and the light source L incident to the inside by the light source L An exit part 21b through which the speckle is emitted to the outside may be formed. In this case, when the object O has a low concentration, it may be advantageous to maximize the transparency of the incident part 21a.

In addition, the container 21 may be provided with a stopper 22 covering the opening formed above. More specifically, the stopper 22 is formed of a scattering body so that the light source L incident into the inside of the container 21 can be scattered in multiple directions, and conical protrusions 51a formed in a conical shape on the inside are formed.

More specifically, the conical protrusion 51a is a protrusion 51 formed to protrude on the inner surface of the stopper 22, and after receiving the object O in the container 21, closes the stopper 22 to rotate in a spiral manner. In this case, at least a portion of the object O overflows from the receiving space of the container 21 to induce the air to flow outside of the container 21 or into the inner space of the stopper 22, thereby allowing air bubbles inside the container 21. It can be prevented from occurring.

For example, the circumferential surface of the conical protrusion 51a is formed with a concave groove H so that the circumferential surfaces of the conical protrusion 51a are inclined at different angles based on the concave groove H, Nano-coating layer (N) may be formed on the circumferential surface and the inner surface of the stopper (22).

And a fastening screw 43 for pressing the second bracket 42 in the direction of the first bracket 41 so that at least a portion of the can be inserted and fixed between the first bracket 41 and the second bracket 42. Can be.

Accordingly, by using the fastening bracket 40, the speckle amplification device 20 can be easily mounted or removed from the information communication terminal 31. For example, the speckle amplification device 20 and the fastening bracket 40 are coupled to the same body, and the information communication terminal 31 between the first bracket 41 and the second bracket 42 of the fastening bracket 40. ), And then tighten the captive screw 43 to press the information communication terminal 31 with the second bracket 42, so that the speckle amplification device 20 can be detachably fastened to the information communication terminal 31. Can be.

In addition, the first bracket 41 may be formed with a through window 41a for transmitting the speckle in the direction of the camera C so as to correspond to the camera C of the information communication terminal 31. More specifically, the through window 41a may be formed at a position corresponding to the exit portion 21b of the container 21 of the speckle amplification apparatus 20.

Accordingly, the speckle amplified by the speckle amplifying apparatus 20 is emitted through the output part 21b of the container 21, and the speckle output is through-hole 41a formed in the first bracket 41. By passing through), the speckle can be measured by the camera (C) installed at a position corresponding to the through-window (41a). Here, various lenses or optical systems such as micro lenses, alternative lenses, objective lenses, and magnification adjusting devices are added to the through-window 41a to minimize the autofocusing effect of the camera C and to overcome the optical distance.
