Disclosed are a spectroscopic device capable of component analysis of an object and an electronic device including the same. More specifically, the present invention discloses a spectroscopic device capable of miniaturizing and carrying a component and analyzing an object thereof, and an electronic device including the same.

Spectrometer is a device that identifies a substance by analyzing the spectrum emitted from the substance or the spectrum absorbed by the substance, and is used in various fields such as environmental engineering, chemistry, pharmacy, and agriculture.

In general, a spectrometer is a light source for generating light of a constant intensity, a monochromator for dispersing light of continuous wavelengths from a light source for each wavelength, and a monochromator, and a sample part for containing a sample. ) And a detector for converting an optical signal into an electrical signal.

As a light source, a tungsten lamp, a tungsten halogen lamp, a deuterium lamp, or a xenon lamp is mainly used.

However, these lamps have a high power consumption and heat dissipation, and thus are limited in portable use. In addition, these lamps do not scan light of a specific wavelength, but scan light of a full wavelength, so a monochromator must be provided, which causes a problem in that there is a limit in miniaturizing a spectroscopic device.

The technical problem to be solved by the present invention is to provide a spectroscopic device that can be miniaturized and portable to enable the component analysis of the object and an electronic device including the same.

In order to solve the above problems, a portable spectrometer according to an embodiment includes a light source unit including a plurality of light sources for scanning light of different wavelengths to the object; And a spectroscopic module including a light detector for acquiring reflected light reflected from the object to obtain a light spectrum of the object, wherein the plurality of light sources are configured such that the optical axes of each of the plurality of light sources intersect at a predetermined point. Characterized in that arranged on the basis of the light sensing unit.

The plurality of light sources are disposed at the same distance with respect to the position of the light detector.

The plurality of light sources are arranged in a line spaced apart at predetermined intervals so as to move away from the position of the light detector.

The point is a position where the object is disposed.

The apparatus further includes a distance detecting unit detecting a distance from the sample unit containing the object.

The apparatus may further include an output unit configured to output object information obtained based on a comparison result between the distance sensed by the distance detector and a reference distance or an optical spectrum of the object.

The object information is obtained according to a result of comparing the light spectrum information obtained by the light sensing unit with the light spectrum information of the light spectrum table, and the light spectrum table includes light spectrum information of a plurality of objects.

The controller may further include sequentially controlling the plurality of light sources according to a control command, or sequentially controlling the plurality of light sources selected from the plurality of light sources.

One side of the spectroscopic module is formed with a seating groove for seating the sample portion containing the object.

According to the present invention as described above, the following effects can be obtained. However, effects obtained through the present invention are not limited to the effects described below.

First, since a plurality of light emitting diodes for irradiating light of a specific wavelength is used as a light source, it is not necessary to provide a monochromator, thereby miniaturizing the spectrometer, thereby providing a portable spectrometer.

Second, since a plurality of light emitting diodes are used as light sources instead of expensive lamps, the manufacturing cost of the spectrometer can be reduced.

Third, since the wavelength of the light emitted to the object may be adjusted by the spectrometer for component analysis, the component analysis of various objects may be performed using one spectrometer.

Meanwhile, the spectrometer 300 may be an individual device (portable) used alone, but is not limited thereto, and may be used in combination with another electronic device such as a refrigerator or a smart phone.

The server 100 receives light spectrum information about an object from the spectrometer 300 through a wired or wireless network. The received optical spectrum information is analyzed to obtain information about the object (hereinafter referred to as 'object information'), and the acquired object information is transmitted to the spectrometer 300 through the wired / wireless network.

Here, the object information may include identification information for identifying the type of the object and information on whether the object is harmful. However, the object information is not necessarily limited to those illustrated, but may also include other types of information.

FIG. 2 is a diagram illustrating the configuration of the server 100 shown in FIG. 1.

2, the server 100 includes a communication unit 110, an analysis unit 120, and a database 130.

The communication unit 110 communicates with the spectroscopic apparatus 300 capable of component analysis of the object through a wired or wireless network. For example, the communication unit 110 receives the light spectrum information of the object from the spectroscopic device 300 capable of component analysis of the object, and analyzes the information of the object obtained by analyzing the light spectrum information. 300). To this end, the communication unit 110 supports a wired communication method and / or a wireless communication method.

Referring to FIG. 3, it can be seen that the first object F1 and the second object F2 have different light spectra. In detail, in the light spectrum of the first object F1, the light intensity of the long wavelength band (exemplarily around 700 nm) is about 10, and the light intensity is superior to the other bands. On the other hand, in the light spectrum of the second object F2, the light intensity of the light in the middle band (exemplified around 300 nm) is about 10, and the light intensity is superior to other bands. That is, each object may have a unique light spectrum different from each other, and the server 100 may obtain object information by analyzing the light spectrum of each object.

FIG. 4 is a diagram for describing a process of acquiring object information based on a light spectrum measured by a spectroscopic apparatus 300 capable of component analysis of an object.

On the left side of FIG. 4 is an optical spectrum table 141. The "type" of the object is listed on the horizontal axis of the light spectrum table 141. The "type" for each object is listed on the vertical axis of the object information table 141. Here, "type" means values that can characterize the unique light spectrum of each object. For example, the type indicates in which wavelength band of the light spectrum the dominance of the light, how the light spectrum fluctuates with increasing or decreasing wavelength, what is the overall intensity of the light spectrum, or the average of the light per wavelength band of the light spectrum. The intensity may include such values as, but is not necessarily limited to, those illustrated. In the following description, as values that can characterize the unique light spectrum of each object, the average intensity of light for each wavelength band of the light spectrum will be described as an example.

Four types (A, B, C, and D) are illustrated in the object information table 141 of FIG. 4. Here, 'type A' refers to the average intensity of light in the shortest wavelength band of the light spectrum measured for a given object. 'Type B' refers to the average intensity of light in the wavelength band longer than 'Type A', 'Type C' refers to the average intensity of light in the wavelength band longer than 'Type B', and 'Type D' means 'Type C' Means the average intensity of light in the longer wavelength band. That is, 'type D' refers to the average intensity of light in the longest wavelength band among light spectra measured for a given object.

4 illustrates a value 142 for each type of light spectrum of the first object F1 and a value 143 for each type of light spectrum of the second object F2.

As illustrated in FIG. 4, when values of the light spectrum of the first object F1 are 'a1', 'b1', 'c1' and 'd1', respectively, they are stored in the object information table 141. Among the subjects are matched with the type-specific value of the light spectrum of 'melamine'. Therefore, the first object F1 may be identified as 'melamine'.

Similarly, when the value of each type of the light spectrum of the second object (F2) is 'a2', 'b2', 'c2' and 'd2', respectively, this is a 'pig' among the objects stored in the object information table 141. Matches the type-specific value of the meat's light spectrum. Therefore, the second object F2 may be identified as 'pork'.
