Description

TECHNICAL FIELD

[0001] The utility model relates to the field of spectrum detection and analysis technology, more particularly to a spectrum detection probe and a spectrometer. BACKGROUND

[0002] Spectrum detection and analysis technology is an analysis method based on optical principles, which obtains information about the chemical composition and physical properties of a substance by measuring its absorption or reflection of light at different wavelengths.

[0003] Spectrum detection and analysis usually uses a spectrum detection probe to emit light from a light source through an optical fiber built into the spectrum detection probe, and the light is emitted at a large divergence angle to the surface of the object to be detected. The reflected or transmitted light from the object to be detected is received by a photodetector, which transmits the electrical signal to the optical signal processing module of the spectrometer for processing and outputs the spectral information of the object to be detected.

[0004] Different types of objects to be detected require spectrum detection probes of different structures, such as transmission probes for liquid detection and reflection probes for solid detection. Flat-end contact probes are not suitable for insertion into bulk materials or powdered objects for measurement, and oblique-end insertion probes cannot be stably inserted into highly fluid powdered objects and are prone to movement or sliding out. In addition, in experimental environments, the object to be detected is usually placed in a separate container on the experimental table before being detected using a spectrum detection probe, which has a single application scenario.

[0013] Optionally, the diameters of the plurality of lenses are different, and the plurality of lenses are arranged on the corresponding lens holders in the order of the diameters from large to small along the propagation direction of the light signal reflected by the light-transmitting containing bin.

[0014] Optionally, the included angle between the light signal emitting assembly and the light-transmitting containing bin is 30°-60°.

[0015] Optionally, the light-shielding housing also has a light signal input port and an electrical signal output port; the light signal input port is located on one side of the light signal emitting component so that the light signal emitted by the light source is transmitted to the light signal emitting component through the light signal input port; the electrical signal output port is located on one side of the light signal receiving component and is used to output the electrical signal converted by the light signal receiving component from the electrical signal output port.

[0016] Furthermore, in a second aspect, this utility model also provides a spectrometer, which includes a light source, a spectral modulator, and a circuit module. The spectral modulator is used to change the energy distribution of light emitted by the light source in the spectrum. The spectrometer also includes the spectral detection probe provided in the first aspect. The output terminals of the circuit module are all connected to the light source and the spectral modulator to drive the light source and the spectral modulator.

[0017] The spectral detection probe of this invention includes a light-shielding housing and a light-transmitting receiving chamber inside the light-shielding housing for storing the object to be detected.

[0019] The spectral detection probe provided by this invention features a light-transmitting chamber that can hold various types of objects to be detected. Utilizing the characteristics of a light-shielding shell, the light signal is transmitted within the probe as much as possible. Furthermore, an angle exists between the light signal emitting component and the light-transmitting chamber, both located inside the shell. The light signal receiving component is positioned along the propagation direction of the light signal reflected from the chamber. This design of the light-shielding shell and its internal structure reduces unnecessary signal loss during transmission between the emitting component, the chamber, and the receiving component, effectively improving detection accuracy. The spectral detection probe provided by this invention can measure solid, liquid, and highly fluid powders or granules. It solves the problems of requiring different probe structures for different types of objects, and the probe's tendency to move or slip out when in contact with or inserted into powdery objects, making stable placement difficult.

[0033] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described are intended to explain this utility model and should not be construed as limiting it.

[0034] The terms "an embodiment," "example," or "trademark" used in this specification refer to a particular feature, structure, or characteristic described in connection with the embodiment itself that may be included in at least one embodiment disclosed in this utility model. The phrase "in an embodiment" appearing in various places throughout the specification does not necessarily refer to the same embodiment.

[0035] In relevant spectral detection and analysis techniques, transmission probes are typically used for liquid detection, taking advantage of the property of light penetrating liquids to measure objects with good light transmittance. For solid detection, especially for objects with high surface reflectivity, reflection probes are used to receive the light signal reflected by the object and perform spectral detection and analysis. When measuring solid objects, flat-end contact probes are only suitable for measuring objects with flat surfaces. Because flat-end contact probes cannot effectively contact the interior of accumulations or powdery objects, they are not suitable for measuring accumulations (such as grains and soil). If angled insertion probes are used, although they can be inserted into accumulations, they are prone to moving or slipping out when dealing with highly fluid powders or granular objects, indicating insufficient stability.

[0036] In view of the above, as a first aspect of this utility model, such as Figures 1-5 As shown, a spectral detection probe 600 is provided. The spectral detection probe 600 includes a light signal emitting component 100 and a light signal receiving component 200. The spectral detection probe 600 also includes a light-transmitting receiving chamber 300 and a light-shielding shell 400. The light signal emitting component 100, the light signal receiving component 200, and the light-transmitting receiving chamber 300 are all disposed within the light-shielding shell 400. The light-transmitting receiving chamber 300 is used to receive the object to be detected 500. The light signal emitting component 100 is used to emit a detection light signal to the light-transmitting receiving chamber 300. The light-transmitting receiving chamber 300 is used to reflect the received detection light to the light signal receiving component 200. The light signal receiving component 200 is used to convert the received light signal into an electrical signal.

[0037] The spectral detection probe 600 provided by this utility model is equipped with a light-transmitting receiving chamber 300, which can store various types of objects to be detected 500. Utilizing the light-shielding properties of the light-shielding shell 400, the light signal is transmitted as much as possible inside the spectral detection probe 600. An angle exists between the light signal emitting component 100 and the light-transmitting receiving chamber 300, which is located inside the light-shielding shell 400. The light signal receiving component 200 is positioned in the direction of propagation of the light signal reflected from the light-transmitting receiving chamber 300. This light-shielding property of the light-shielding shell 400 and its internal structural design reduce unnecessary losses in the transmission of light signals between the light signal emitting component 100, the light-transmitting receiving chamber 300, and the light signal receiving component 200, effectively improving detection accuracy. Simultaneously, the spectral detection probe 600 provided by this utility model can measure solid, liquid, and highly fluid powder or granular objects, solving the problems of different types of objects to be detected 500 requiring different structural types of spectral detection probes 600, and the easy movement and slippage of the spectral detection probe 600 when in contact with or inserted into powdery objects, making stable placement on the object to be detected 500 impossible. Furthermore, when conducting tests in a laboratory setting, it is not necessary to place the object to be tested 500 in a separate container on the experimental table and then adjust the positional relationship between the spectral detection probe 600 and the separate container to obtain the spectral information of the object to be tested 500. The object to be tested 500 can be directly placed into the light-transmitting receiving chamber 300 to complete the spectral detection. In summary, the spectral detection probe 600 provided by this utility model has the characteristics and advantages of supporting multiple types of objects to be tested 500, diverse application scenarios, and strong practicality.

[0038] In this embodiment, the shape of the light-transmitting container 300 is not specifically limited. The shape of the light-transmitting container 300 can be cylindrical, square or other shapes, but it needs to have the characteristic of light transmission. As an optional implementation, the bottom of the light-transmitting container 300 can be a glass window, and the transmittance of the glass window is more than 90%, so as to reduce light loss while realizing the incident and reflected light.

[0039] The light-transmitting receiving chamber 300 is disposed inside the light-shielding housing 400. As one embodiment, the spectral detection probe 600 also includes a receiving chamber clamping member 303, which is disposed inside the light-shielding housing 400. The light-shielding housing 400 has a detection object access port 401, and the receiving chamber clamping member 303 is used to fix the light-transmitting receiving chamber 300 to the detection object access port 401.

[0040] The light-transmitting receiving chamber 300 includes a chamber body 301 and a plug 302. An opening 3011 is formed on the chamber body 301. The plug 302 covers the opening 3011, so that the plug 302 and the chamber body 301 together form a sealed chamber for receiving the object to be tested 500. The plug 302 is detached from the opening 3011, so that the object to be tested 500 is placed in the light-transmitting receiving chamber 300 through the opening 3011.

[0041] The light-transmitting container 300 can hold liquids, solids, powders, or granules awaiting testing, such as an object 500. The opening 3011 and stopper 302 of the light-transmitting container 300 pass through the object access port 401 of the light-shielding housing 400. The bottom of the light-transmitting container 300 is located inside the light-shielding housing 400. When the operator removes the stopper 302, the object 500 can be placed in the container 301. By plugging the opening 3011 with the stopper 302, the light-transmitting container 300 becomes a sealed container for holding the object 500. Figures 3-4 As shown.

[0042] The spectral detection probe 600 includes a light-transmitting housing 300, as well as basic optical signal input and output terminals. As an optional implementation, the spectral detection probe 600 further includes an optical signal transmission medium clamp 103 and a collimating device clamp 104, both disposed within the light-shielding housing 400. The optical signal transmitting assembly 100 includes an optical signal transmission medium 101 and a collimating device 102. The collimating device 102 collimates and expands the optical signal emitted from the optical signal transmission medium 101. The optical signal transmission medium 101 is disposed on the optical signal transmission medium clamp 103, and the collimating device 102 is disposed on the collimating device clamp 104. The collimating device clamp 104 is disposed between the optical signal transmission medium clamp 103 and the light-transmitting housing 300, and the collimating device 102 is disposed between the optical signal transmission medium 101 and the light-transmitting housing 300. As an optional implementation of the optical signal output terminal, the spectral detection probe 600 also includes a detector holder 203 and multiple lens holders 204, both of which are disposed within the light-shielding housing 400; the optical signal receiving component 200 includes a photodetector 201 and multiple lenses 202, the photodetector 201 is disposed on the detector holder 203, and the multiple lenses 202 correspond one-to-one with the multiple lens holders 204, with the lenses 202 disposed on the lens holders 204, and the multiple lens holders 204 are all disposed between the detector holder 203 and the light-transmitting receiving chamber 300, and the multiple lenses 202 are all disposed between the detector and the light-transmitting receiving chamber 300.

[0043] It should be noted that the optical signal transmission medium 101 is optical fiber 1011, more specifically, it can be single-mode optical fiber 1011. The collimating device 102 is not specifically limited, as long as it can collimate and expand the light beam. The collimating device 102 can be a collimating lens or a fiber optic collimator. More specifically, the type of collimating lens is not specifically limited; it can be a Fresnel lens or a general collimating lens. The lens type of the fiber optic collimator is also not specifically limited; it can be a collimating lens, a graded-index self-focusing lens, or other lenses for controlling the beam.

[0044] Regarding the optical signal receiving end of the spectral detection probe 600, the number and type of lenses 202 are not specifically limited in the spectral detection probe 600 proposed in this utility model, as long as they can accurately guide the optical signal reflected by the object to be detected 500 to the receiving end of the photodetector 201. The diameter of the multiple lenses 202 is also not specifically limited, as long as they can be combined to guide the optical signal to the receiving end of the photodetector 201. As an optional implementation, the diameters of the multiple lenses 202 are all different, and the multiple lenses 202 are arranged sequentially on the corresponding lens holders 204 in descending order of diameter along the propagation direction of the optical signal reflected by the light-transmitting receiving chamber 300.

[0045] like Figures 1-2 The spectral detection probe 600 shown has a collimating lens placed at the light-emitting end of a single-mode fiber 1011. The single-mode fiber 1011 is inserted into the optical signal input port 402. The light emitted through the fiber optic connector 1012 is collimated by the collimating lens and transmitted to the object to be detected 500 inside the light-transmitting chamber 300. The light signal reflected by the object to be detected 500 passes through the light-transmitting chamber 300 and is accurately guided to the receiving end of the photodetector 201 after passing through a lens group composed of three Fresnel lenses arranged in descending order of diameter along the direction of light signal propagation. The photodetector 201 converts the light signal into an electrical signal and outputs it from the electrical signal output port 403.

[0046] In order to enable the photodetector 201 to receive as much diffuse reflected light as possible from the object 500 to be detected, as an optional implementation, the angle between the optical signal emitting component 100 and the light-transmitting receiving chamber 300 is 30° to 60°. In this embodiment, the angle between the optical signal emitting component 100 and the light-transmitting receiving chamber 300 is set to 45°.

[0047] like Figure 5The light-shielding housing 400 of the spectral detection probe 600 shown has an optical signal input port 402 and an electrical signal output port 403. The optical signal input port 402 is located on one side of the optical signal emitting component 100 so that the optical signal emitted by the light source 700 is transmitted to the optical signal emitting component 100 through the optical signal input port 402. The electrical signal output port 403 is located on one side of the optical signal receiving component 200 and is used to output the electrical signal converted by the optical signal receiving component 200 from the electrical signal output port 403.

[0048] As a second aspect of this utility model, a spectrometer is provided, which includes a light source 700, a spectral modulator 800, and a circuit module 900. The spectral modulator 800 is used to change the energy distribution of the light emitted by the light source 700 in the spectrum. The spectrometer also includes the spectral detection probe 600 provided in the first aspect. The output terminals of the circuit module 900 are connected to the light source 700 and the spectral modulator 800 to drive the light source 700 and the spectral modulator 800. The input terminals of the circuit module 900 are connected to the spectral detection probe 600 to receive the electrical signals transmitted by the spectral detection probe 600 and output the spectral information of the object 500 to be detected.

[0049] Figure 6 This is a schematic diagram of the spectrometer structure provided by this utility model, and... Figure 6 The diagram details the propagation paths of the optical and electrical signals within the spectrometer. Circuit module 900 sends electrical signals to light source 700 and spectral modulator 800, driving light source 700 to emit light and spectral modulator 800 to begin operation. The energy distribution of the light signal emitted by light source 700 is remodulated by spectral modulator 800, and the modulated light signal is transmitted to spectral detection probe 600. The light signal emitting component 100 within spectral detection probe 600 illuminates the object 500 to be detected. The light signal reflected from the object 500 is received by the light signal component within spectral detection probe 600, converted into an electrical signal, and output by spectral detection probe 600 to circuit module 900. Circuit module 900 processes the electrical signal and calculates the spectral information of the object 500. The light source 700 of the spectrometer can be a superluminescent diode or other broadband light source 700.

[0050] It should be noted that the circuit modulation module includes a driver module 901 and a signal processing module 902, such as... Figure 7 As shown. The driving module 901 is used to drive the light source 700 and the spectral modulator 800; the signal processing module 902 is connected to the output terminal of the photodetector 201 in the spectral detection probe 600, and acquires the relevant spectral data of the object to be detected 500 according to the electrical signal received from the photodetector 201.

[0051] A spectral modulator 800 is positioned between the light source 700 and the spectral detection probe 600 to alter the energy distribution of the light emitted by the light source 700 across the spectrum. As an optional implementation, such as... Figure 8 As shown, the spectral modulator 800 includes multiple active tunable spectral units 801, with the output of the previous active tunable spectral unit 801 connected to the input of the next active tunable spectral unit 801. The active tunable spectral unit 801 includes a beam splitting unit, where the beam splitting element can be various common waveguide beam splitters, such as directional couplers, multimode interferometers, etc.

[0052] Figure 8 The given spectral modulator 800 consists of four active tunable spectral units 801. The first active tunable spectral unit 801 is an asymmetric Mach-Zehnder interferometer, with a phase modulator 802 on each of its interferometer arms. The second to fourth active tunable spectral units 801 are microring resonators, each with a different ring length and a phase modulator 802. The optical signal is transmitted through an optical waveguide to two interferometer arms of the asymmetric Mach-Zehnder interferometer. By changing the parameters of the phase modulators 802 on the interferometer arms, the phase difference / optical path difference between the two interferometer arms is altered, causing interference between the two optical signals at the optical waveguide, thus controlling the intensity of the optical signal. The optical signal processed by the Mach-Zehnder interferometer enters the microring structure, where the microring performs wavelength selection on the input optical signal, coupling a specific wavelength of optical signal to the microring. Through the synergistic effect of these two components, flexible tuning and control of various parameters of the optical signal (such as wavelength and intensity) can be achieved. In addition to the spectral modulator 800... Figure 8 In addition to the given embodiments, the structure can also be a cascaded Mach-Zehnder interferometer or a cascaded microring.
