Particularly, such spectroscopic imaging technology has been verified for its usefulness in diagnosis of diseases occurring in various parts of the human body such as skin, ear, digestive organs, and is being commercialized.

Spectral imaging analysis technology can analyze spectral information of image and image pixel unit unlike existing spectral analysis technology, thus enabling more reliable analysis.

However, in the case of conventional spectroscopic imaging technology, a light source for image acquisition, an active adjustment filter capable of electrical adjustment for spectral filtering of a light source, or an optical bandpass filter capable of selectively passing light of a specific wavelength band is used . Particularly, when an optical band pass filter is used, the filters are classified according to specific bandwidths and must be purchased separately, and the volume of the spectral imaging system becomes large depending on the number of filters.

In addition, the conventional gonioscopic apparatus photographs the state of the inside of the ear through a smartphone or a magnifying glass, and diagnoses whether or not otitis media occurs by checking with eyes. Therefore, it is difficult to detect the diagnosis of otitis media in the general population or the occurrence of other diseases when the symptoms of otitis media do not occur clearly.

Figure 1 shows a schematic diagram of a system for diagnosing otitis media using mobile-based spectroscopic imaging in accordance with an embodiment of the present invention.

According to one embodiment of the present invention, an otitis media diagnosis (and / or management) system (hereinafter referred to as an otitis media diagnosis system 10) using mobile based spectroscopic imaging is a device And a controller 103 for providing a light source to the gonioscopic apparatus 101 and controlling the gonioscopic apparatus 101 and diagnosing whether or not it has an otitis media.

According to one embodiment, the gonioscope device 101 includes an illuminator for illuminating light for diagnostic purposes to an object (e.g., a patient's middle ear), and an electromagnetic wave emitted (or reflected) from the object (e.g., infrared and / Light rays), and diagnose the disease based on the detected electromagnetic waves. Here, the illumination unit may include at least one filter, and may be capable of spectroscopically emitting the light collected from the light source through the included filter. At this time, the emitted light can be irradiated to the target object. Here, when at least one lens (e.g., a concave lens) is included in the output end of the illumination unit, light emitted through the included lens can be irradiated on the object. Also, at least one optical fiber and a focusing lens may be included at the output end of the illumination unit, and the light emitted through the included optical fiber may be directly irradiated to the object.

According to one embodiment, the filter included in the illumination unit of the gonioscopy apparatus 101 may include at least one non-linear filter and / or a linear variable filter (hereinafter, a linear filter). Here, when a plurality of nonlinear filters are used in the gonioscopy apparatus, the nonlinear filter can be changed (or replaced) to filter light of a specific wavelength to be spectroscopically analyzed. According to another embodiment, when a linear filter is used in a gonioscopic device, it is possible to change the position at which the light is irradiated to the linear filter (e.g., move the linear filter) to filter the light of a specific wavelength to be spectroscopically analyzed.

The gonioscopy apparatus 101 may include at least one communication unit and may be connected to the control apparatus 103 to receive control information from the control apparatus 103. [ For example, when the gonioscopic apparatus 101 includes a linear filter, coordinate information for moving the linear filter may be received. Alternatively, the gonioscopy apparatus 101 may transmit the filter information in which the specification of the linear filter is recorded to the control apparatus 103. [ In addition, the gonioscopic apparatus 101 uses information for diagnosing a patient's disease (for example, otitis media) using electromagnetic waves, for example, wavelength information of an electromagnetic wave according to a disease, or spectral information of an electromagnetic wave according to a disease The disease diagnosis information may be transmitted to the control device 103 together with the filter information. Here, the control information may be data (or packet) in a format used in a communication method connected to the control device 103. [

The gonioscopic apparatus 101 can detect electromagnetic waves such as visible light and infrared band light reflected or emitted from the object after the light emitted through the filter is irradiated on the object. According to one embodiment, the gonioscopy apparatus 101 can detect an electromagnetic wave and confirm the spectrum of the electromagnetic wave in pixel units. For example, the gonioscopy apparatus 101 may include an infrared temperature sensor. The gonioscopic apparatus (101) can detect the infrared wavelength through the infrared temperature sensor and confirm the body temperature based on the infrared wavelength. According to another embodiment for confirming the spectrum in the gonioscopic apparatus 101, the spectroscopy can be confirmed for an electromagnetic wave of a specific wavelength passing through at least one color selection mirror (for example, a dichroic mirror included in the gonioscopic apparatus 101) It is possible.

The gonioscopic apparatus 101 can separate and reflect electromagnetic waves of a specific wavelength through a color selection mirror, and the electromagnetic waves passed through the mirror can be transmitted to a camera (or an image sensor) of the control device 103. The color discriminating mirror included in the gonioscopic apparatus 101 can pass or reflect electromagnetic waves of a specific wavelength and emit electromagnetic waves of a specific wavelength to the outside of the gonioscopic apparatus 101 using two or more color discriminating mirrors .

The control device 103 may include at least one communication unit and may be connected to the gonioscopy apparatus 101 to receive filter information from the gonioscopy apparatus. The control device 103 may transmit the coordinate information (and / or control information) for controlling the linear filter included in the gonioscopy device 101 to the gonioscopy device 101 based on the filter information.

The control device 103 can receive electromagnetic waves emitted from the gonioscopy device 101 using a camera (and / or an image sensor). Here, the reception of the electromagnetic wave emitted from the gonioscope apparatus 101 is to transmit the image of the electromagnetic wave and the object filtered through the detection unit to the control device 103 Quot;) camera. ≪ / RTI > The control device 103 can compare the received electromagnetic wave (and / or image) with the disease diagnosis information to check whether the patient is ill or not and output the confirmed information. For example, the control device 103 can confirm the wavelength of the electromagnetic wave received through the camera and compare the wavelength with the wavelengths included in the disease diagnosis information, thereby confirming the information corresponding to the wavelength of the received electromagnetic wave.

The control device 103 may display the confirmed information through an output device such as the display 105. [ For example, in the case of determining otitis media, the control device 103 can display at least a part of the spectrum of the received electromagnetic wave on the display 105, and can display the degree of otitis media of the patient together. At this time, the control device 103 may display the spectrum of the normal state and / or the spectrum of the otitis media on the display 105 based on the filter information and / or the disease diagnosis information received from the gonioscopy device 101 . In addition, when the control device 103 displays the spectrum of the otitis media, it may display at least a part of the spectrum separated according to the stage of the otitis media.

It is apparent that the definition of the above-described device can be applied to the control device 103 in Fig. 1 and the following description. For example, the control device 103 may be a smart phone including a communication unit and a light source (e.g., flash, flash) and a camera (or an image sensor).

2 shows a schematic view of an illumination unit of a mobile-based spectroscopic imaging apparatus according to another embodiment of the present invention.

The illuminating unit 101-1 of the gonioscopy apparatus 101 converts light received (or collected) from the light source 107 of the control device 103 into a linear variable filter 123, or a linear spectral filter, hereinafter referred to as a linear filter), and then emits the spectral light. Here, the linear variable filter 123 may have a characteristic in which the spectrum linearly changes in response to a linear change in the position of the beam passing through the linear filter. For example, a linear variable bandpass filter may be a coated optical filter and may have spectral characteristics that vary linearly over the entire length of the filter. Linear variable bandpass filters have high transmittance in narrow bandwidths and deep blocking performance for unwanted light, maximizing system performance at the required wavelengths. Accordingly, the spectral response can be adjusted only by moving the position of the linear filter 123 based on the position where the beam is irradiated. According to another embodiment, a Linear Variable Edge Filter may be used individually or in pairs to selectively block or pass particular wavelengths. Linear variable edge filters can be used as longpass, shortpass or bandpass filters. Longpass edge filters transmit longer wavelengths than cut-on wavelengths and shortpass edge filters transmit shorter wavelengths than cut-off wavelengths. The bandpass edge filter can be used in combination with a longpass edge filter and a shortpass edge filter. That is, the linear variable edge filter can serve as a laser line filter or a variable bandpass filter and can control the center wavelength and bandwidth.

The light input unit receiving light from the light source 107 may be provided as an optical fiber 110. Referring to FIG. The optical fiber 110 may receive light from the light source 107 and emit it to the linear filter 123. At least one lens 113 (e.g., a focusing lens) may be attached to the end of the optical fiber 110 in the direction of the light source in order to collect light emitted from the light source 107. At this time, the intensity of light output from the optical fiber 110 can be determined based on the diffraction limit of the lens 113 attached to the optical fiber 110. The light received through the lens 113 may be output to the end 115 of the optical fiber 110 in the direction of the linear filter 123 in the form of a beam.

The light emitted from the end 115 of the optical fiber 110 may be emitted to the linear filter 123 through the first spatial filter 125 of the filter unit 119. Here, the first spatial filter 125 may function to process the size of the beam emitted from the optical fiber 110 based on the hole inner diameter. The processed beam may then be split through a linear filter 123 and emitted into a second spatial filter. Here, the linear filter 123 may be fabricated such that the central wavelength of the light passing through the linear filter 123 changes linearly in accordance with the change in the position where the light is irradiated. For example, when changing the position of the linear filter 123 irradiated with the processed beam through the first spatial filter 125, the central wavelength of light passing through the changed position may be determined. According to one embodiment, the center wavelength of light passing through the linear filter 123 from the beam emitted through the first spatial filter 125 is determined by the position of the linear filter 123 (e.g., The y-axis value of the reference point (e.g., 123)), can be changed linearly.

The range of the central wavelength can be determined through the second spatial filter by the light that is spectrally filtered through the linear filter 123. For example, the light that is spectrally filtered through the linear filter 123 may be in a state of being spectrally separated into various wavelengths depending on the characteristics of the filter. The range of the central wavelength that is output based on the hole inner diameter of the second spatial filter can be determined. By controlling the hole inner diameters of the second spatial filter as described above, it is possible to control the wavelength range of the finally output light from the spectroscopic light. At least one lens 117 may be disposed at the output end of the filter unit 119 to expand or focus the range of light irradiated on the object. The spectrally illuminated light may be passed (or reflected) to at least one of a lens, an optical fiber, at least one filter (e.g., a mirror and / or a color picker mirror 135)

According to an embodiment of the present invention, a method and apparatus for changing the position of the linear filter 123 included in the filter unit 119 can be provided. For example, the linear filter 123 may be coupled to a motor 141 to move (e.g., move the y-axis value of the linear filter 123 shown in Figure 1) based on the motion of the motor 141 . At this time, the motor 141 for moving the linear filter 123 can move the linear filter 123 based on the control information received from the control device 103. The lighting unit 101-1 and the control unit 103 may include a communication unit and the lighting unit 101-1 may include control information for moving the motor 141 from the control unit 103 through the communication unit, Lt; / RTI > For example, the control information may include coordinate information to which the linear filter 123 will move. The motor 141 can determine the movement of the linear filter 123 based on the received control information. Here, the control information may be data (or packet) in a format used in a communication method connected to the control device 103. [ It is apparent that the definition of the above-described device can be applied to the control device 103 in Fig. 1 and the following description. For example, the control device 103 may be a smart phone including a communication unit and a light source (e.g., flash).

According to another embodiment, the filter unit 119 of the illumination unit 101-1 may be configured with the first spatial filter 125 removed. The filter unit 119 may be composed of a linear filter 123 and a spatial filter 121 for spectrally separating the beam emitted from the end 115 of the optical fiber 110.

1, the beam size emitted from the optical fiber 110 is processed through the first spatial filter 125 and irradiated to the linear filter 123 FIG. On the other hand, when the first spatial filter 125 is removed, the beam size irradiated to the linear filter 123 can be determined based on the optical fiber 110. For example, the beam size irradiated on the linear filter 123 may be determined according to the core inner diameter of the optical fiber 110. [ That is, the illumination unit 101-1 can selectively apply the optical fibers having different inner diameters of the core, and the beam size irradiated to the linear filter 123 can be controlled according to the core inner diameter of the applied optical fiber. At this time, the beam size and luminous intensity output from the optical fiber 110 can be determined based on the diffraction limit of the lens 113 attached to the optical fiber 110 and / or the inner diameter of the core 131 of the optical fiber 110.

 FIG. 3 shows a schematic view of a detection section of a mobile-based spectral imaging inspection apparatus according to another embodiment of the present invention.

According to an embodiment of the present invention, the detection unit 101-2 of the gonioscopy apparatus 101 can detect an electromagnetic wave emitted from an object (e.g., middle ear). When the detection unit 101-2 includes a lens, electromagnetic waves can be collected through the lens. The collected electromagnetic waves can be separated into electromagnetic waves of a specific wavelength through at least one color selection mirror included in the detection unit 101-2.
