[0051] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0052] In the application scenario of collecting fluorescence signals, since fluorescence signals are natural light that is uniformly diffused in space and has no definite directionality, it is difficult to collect fluorescence signals efficiently. In traditional technologies, methods for collecting fluorescence signals can be divided into the following categories:

[0053] The first method is to change the end face of the collection fiber. This method changes the flat end face of the optical fiber that collects the fluorescence signal into other shapes. For example, the end face of the optical fiber is heated by a high-temperature flame to melt it and then naturally cool it to form a spherical shape. This method is equivalent to seamlessly adding a convex lens to the end face of the collection fiber, thereby improving the collection efficiency of fluorescence. However, this method has limited effect on improving the collection efficiency. Moreover, due to the poor consistency of the spherical end face of the collection fiber, the size and shape of the molten ball cannot be accurately controlled, so it cannot be actually mass-produced and applied.

[0054] The second method is to increase the number of collecting optical fibers. This method increases the number of optical fibers collecting fluorescence, densely arranging the collection end faces of multiple optical fibers into an array and placing them as close to the fluorescence signal source as possible. This method is equivalent to increasing the cross-sectional area of ​​the collecting optical fiber and improving the fluorescence collection efficiency. However, this method increases the complexity of the device structure and the volume, weight and cost of the device, and its effect on improving the collection efficiency is limited.

[0055] The third method is to add a coupling lens. This method adds a lens on one side of the fluorescent material to collect and converge the spatially divergent fluorescence, and then couple it to the optical fiber that collects the fluorescent signal, thereby improving the fluorescence collection efficiency through the convergence ability of the lens. However, this method not only increases the complexity of the device structure and the volume, weight and cost of the device, but also because the shape and volume of the fluorescent working material are different, there are fewer scenarios that allow the addition of a focusing lens, so its applicability is poor.

[0056] In summary, the conventional technology has the problem of low optical signal collection efficiency. In view of this, an embodiment of the present application provides an optical signal collection device for improving the optical signal collection efficiency.

[0057] In an exemplary embodiment, Figure 1As shown, an optical signal collecting device is provided, comprising:

[0058] The coreless optical fiber 10 has one end 101 which is a free end. The coreless optical fiber 10 is used to receive the optical signal emitted by the luminescent material 30 .

[0059] The collecting optical fiber 20, one end 201 of the collecting optical fiber is fused with the other end 102 of the coreless optical fiber to form a fusion region 40, and the other end 202 of the collecting optical fiber is used to connect to the signal processor 50; the collecting optical fiber 20 is used to receive the optical signal through the fusion region 40 and transmit the optical signal to the signal processor 50.

[0060] Among them, the coreless optical fiber 10 is an optical fiber without a traditional core central glass core, but only a cladding and a coating layer. It can transmit optical signals by reflection in the air, reduce the optical energy density at the optical signal receiving end face, reduce back reflection, and is suitable for different usage requirements.

[0061] Optionally, in this embodiment, a coreless optical fiber with a stripped coating can be selected. Since the numerical aperture of the coreless optical fiber with a stripped coating is relatively large, it can collect optical signals in a larger range of spatial angles, thereby improving the coupling efficiency of the fluorescent signal and the collection rate of the fluorescent signal. Therefore, in this embodiment, the coreless optical fiber 10 can be used to receive the optical signal emitted by the luminescent material 30. Among them, one end 101 of the coreless optical fiber is a free end for receiving the optical signal, and the other end 102 of the coreless optical fiber is used to connect with the collection optical fiber 20. In theory, the numerical aperture NA of the coreless optical fiber with a stripped coating can be 1.0, which can collect all divergent optical signals in the entire half space, greatly improving the coupling efficiency of the optical signal and the coreless optical fiber 10.

[0062] As an optional embodiment, the luminescent material 30 may be a fluorescent luminescent material, and the light signal emitted by the luminescent material 30 may be a fluorescent signal. Fluorescence refers to the emission of light with a longer wavelength when certain substances are irradiated by incident light that meets the excitation conditions, and when the irradiation stops, the fluorescence disappears. It should be noted that the divergence range of the fluorescent signal emitted by the fluorescent luminescent material is relatively large and the divergence angles are multiple, and the energy of the fluorescent signal is distributed within the entire spatial angle range of 4π.

[0063] The collection optical fiber 20 is an optical fiber for receiving optical signals. Optionally, the collection optical fiber 20 can be a multimode collection optical fiber. One end 201 of the collection optical fiber is used to connect to the other end 102 of the coreless optical fiber, and the other end 202 of the collection optical fiber is used to connect to the signal processor 50.

[0064] It should be noted that the numerical aperture of the coreless optical fiber 10 is greater than that of the collection optical fiber 20. Therefore, compared with the collection optical fiber 20, the coreless optical fiber 10 has a larger receiving angle for receiving optical signals, thereby being able to receive more optical signals. Therefore, in order to improve the collection rate of the collection optical fiber 20 for optical signals, the coreless optical fiber 10 and the collection optical fiber 20 can be fused to form a fusion region 40, that is, one end 201 of the collection optical fiber is fused to the other end 102 of the coreless optical fiber, so that the optical signal received by the coreless optical fiber 10 is transmitted to the collection optical fiber 20 through the fusion region 40.

[0065] As an optional embodiment, the numerical aperture of the coreless optical fiber 10 is greater than the numerical aperture of the fusion region 40, and the numerical aperture of the fusion region 40 is greater than the numerical aperture of the collection optical fiber 20. Therefore, the number of mode fields supported by the coreless optical fiber 10 is greater than the number of mode fields supported by the fusion region 40, and the number of mode fields supported by the fusion region 40 is greater than the number of mode fields supported by the collection optical fiber 20, that is, the fiber waveconductivity of the coreless optical fiber 10 is greater than the fiber waveconductivity of the fusion region 40, and the fiber waveconductivity of the fusion region 40 is greater than the fiber waveconductivity of the collection optical fiber 20. Fiber waveconductivity refers to the ability of light to be transmitted in an optical fiber, which can also be called the mode field diameter ratio. The fiber waveconductivity depends on the structure and material properties of the optical fiber, including the refractive index distribution of the core and cladding, the length and diameter of the optical fiber, and the dispersion and loss characteristics of the optical fiber material.

[0066] In this embodiment, the coreless optical fiber 10 and the collecting optical fiber 20 can be fused by a fusion splicer, that is, the other end 102 of the coreless optical fiber is fused with one end 201 of the collecting optical fiber to form a fusion region 40. When one end 101 of the coreless optical fiber receives the optical signal emitted by the luminescent material 30, the optical signal is transmitted to the fusion region 40, and then the received optical signal is transmitted to one end 201 of the collecting optical fiber through the fusion region 40. The collecting optical fiber 20 can transmit the optical signal to the signal processor 50 through the other end 202 of the collecting optical fiber, so that the signal processor 50 can process the optical signal.

[0067] In the above-mentioned optical signal collection device, the optical signal collection device includes a coreless optical fiber and a collection optical fiber, one end of the coreless optical fiber is a free end, the coreless optical fiber is used to receive the optical signal emitted by the luminescent material, one end of the collection optical fiber is fused with the other end of the coreless optical fiber to form a fusion region, the other end of the collection optical fiber is used to connect to the signal processor, the collection optical fiber is used to receive the optical signal through the fusion region, and transmit the optical signal to the signal processor. Since more optical signals can be received through the coreless optical fiber, and the angle of the optical signal can be homogenized, the homogenized optical signal can be transmitted to the fusion region, further, the homogenized optical signal can be homogenized again through the fusion region, so that the homogenized optical signal can enter the collection optical fiber with less loss, thereby improving the coupling efficiency of the collection optical fiber to the optical signal and improving the collection rate of the optical signal.

[0068] In an exemplary embodiment, Figure 2 As shown, the diameter of the coreless optical fiber 10 is equal to the diameter of the collection optical fiber 20 .

[0069] The collection optical fiber 20 includes an optical fiber cladding 203 and an optical fiber core 204 . The optical fiber cladding 203 wraps the optical fiber core 204 . The diameter of the coreless optical fiber 10 is equal to the diameter of the optical fiber cladding 203 .

[0070] It should be noted that in order to enable the fusion region 40 to transmit the optical signal received by the coreless optical fiber 10 to the collecting optical fiber 20, it is necessary to ensure that the size of the fusion region 40 is equal to the size of the coreless optical fiber 10 and the collecting optical fiber 20. Therefore, the diameter of the coreless optical fiber 10 is equal to the diameter of the collecting optical fiber 20.

[0071] Furthermore, the collection optical fiber 20 may be composed of an optical fiber cladding 203 and an optical fiber core 204 , and therefore, the diameter of the coreless optical fiber 10 is equal to the diameter of the optical fiber cladding 203 .

[0072] In this embodiment, the diameter of the coreless optical fiber is equal to the diameter of the collecting optical fiber, thereby ensuring that the fusion area formed by fusing one end of the collecting optical fiber with the other end of the coreless optical fiber can be equal in size to the collecting optical fiber and the coreless optical fiber, thereby reducing the loss during optical signal transmission.

[0073] In an exemplary embodiment, the coreless optical fiber 10 is an optical fiber with a coating removed, and after the coating is removed, one end 201 of the collection optical fiber is fused with one end 101 of the coreless optical fiber to form a fusion region 40 .

[0074] It is understandable that after removing the coating layer of the coreless optical fiber 10, the numerical aperture of the coreless optical fiber 10 can be increased, thereby increasing the angle of the light signal that can be received. Therefore, in the embodiment of the present application, the coating layer of the coreless optical fiber can be removed by stripping technology.

[0075] In order to perform fusion splicing with the coreless optical fiber 10 , it is also necessary to remove the coating layer of one end 201 of the collection optical fiber, and then use a fusion splicer to fusion splice one end 201 of the collection optical fiber with one end 101 of the coreless optical fiber to form a fusion region 40 .

[0076] In this embodiment, the coreless optical fiber is an optical fiber with the coating removed. After the coating is removed from one end of the collecting optical fiber, it is fused with one end of the coreless optical fiber to form a fusion region. Since the coating of the coreless optical fiber is removed, the collection rate of the optical signal of the coreless optical fiber can be increased. Moreover, by removing the coating from one end of the collecting optical fiber, it can be fused with one end of the coreless optical fiber to form a fusion region.

[0077] In an exemplary embodiment, Figure 3 As shown, an optical signal collection system is provided, which includes an optical signal collection device and a luminescent material, wherein the luminescent material is arranged on one side of the free end of the coreless optical fiber in the optical signal collection device; the luminescent material is used to emit an optical signal; and the optical signal collection device is used to collect the optical signal through the coreless optical fiber.

[0078] Among them, the coreless optical fiber is an optical fiber used to collect optical signals in the signal collection device. In this embodiment, the luminescent material that emits the optical signal can be arranged on a side close to the free end of the coreless optical fiber, so that the coreless optical fiber can collect the optical signal, thereby realizing the collection of the optical signal by the optical signal collection device.

[0079] As an optional implementation, Figure 4 As shown, the optical signal collection system may also include an excitation optical fiber, an excitation light source and a lens; one end of the excitation optical fiber is close to the luminescent material, and the lens is arranged between the other end of the excitation optical fiber and the excitation light source; the excitation light source is used to emit an excitation light beam; the lens is used to collimate the excitation light beam; the excitation optical fiber is used to receive the collimated coupled excitation light beam, and transmit the collimated coupled excitation light beam to the luminescent material, so that the luminescent material emits an optical signal under the action of the collimated coupled excitation light beam.

[0080] It can be understood that since the excitation light source can emit an excitation light beam, and the lens can collimate and couple the excitation light beam, thereby focusing the excitation light beam, the collimated coupled excitation light beam can enter the excitation optical fiber, thereby transmitting the collimated coupled excitation light beam to the luminescent material, so that the luminescent material emits a light signal under the action of the collimated coupled excitation light beam, thereby enabling the light signal collection device to receive the light signal.

[0081] Please continue to refer to Figure 4The optical signal collection system may also include a phototube and a signal processor; the receiving end of the phototube is connected to the collection optical fiber in the optical signal collection device, and the output end of the phototube is connected to the signal processor; the optical signal collection device is used to transmit the collected optical signal to the phototube; the phototube is used to convert the optical signal into an electrical signal, and transmit the electrical signal to the signal processor; the signal processor is used to process the electrical signal to obtain a signal detection result.

[0082] It can be understood that since the excitation light source can emit an excitation light beam, and the lens can collimate and couple the excitation light beam, thereby focusing the excitation light beam, the collimated coupled excitation light beam can enter the excitation optical fiber, thereby transmitting the collimated coupled excitation light beam to the luminescent material, so that the luminescent material emits a light signal under the action of the collimated coupled excitation light beam, thereby enabling the light signal collection device to receive the light signal.

[0083] In this embodiment, the optical signal collection system includes an optical signal collection device and a luminescent material. The luminescent material is arranged on one side of the free end of the coreless optical fiber in the optical signal collection device. The luminescent material is used to emit an optical signal, and the optical signal collection device is used to collect the optical signal through the coreless optical fiber. Since the coreless optical fiber has a higher data aperture, it can receive optical signals at more angles, thereby improving the collection rate of the optical signal collection device for optical signals.

[0084] In an exemplary embodiment, Figure 5 As shown, a method for collecting optical signals is provided, and the method for collecting optical signals is applied to the above optical signal collection system, and the optical signal collection system includes an optical signal collection device, and the method includes:

[0085] Step 501, receiving an optical signal through a coreless optical fiber in an optical signal collecting device, where the optical signal is emitted by a luminescent substance.

[0086] It should be noted that in the embodiment of the present application, the optical signal collection system may also include a network card and a controller. The computer device can send control instructions to the network card, and the network card converts the control instructions and sends them to the controller. The controller can control the collection of optical signals in the optical signal collection device.

[0087] In this embodiment, the optical signal emitted by the luminescent material can be received by the coreless optical fiber in the optical signal collecting device.

[0088] Step 502: receiving the optical signal transmitted through the fusion region through the collection optical fiber in the optical signal collection device, where the fusion region is obtained by fusion-joining one end of the collection optical fiber and the other end of the coreless optical fiber.

[0089] It is understandable that the optical signal received by the coreless optical fiber can be transmitted to the fusion region, and the fusion region can transmit the optical signal to the collection optical fiber. Therefore, in this embodiment, the optical signal transmitted through the fusion region can be received by the collection optical fiber in the optical signal collection device.

[0090] In this embodiment, the computer device controls the coreless optical fiber to receive the optical signal emitted by the luminescent material, and then can control the collecting optical fiber to receive the optical signal transmitted through the fusion region. Since the fusion region is obtained by fusing one end of the collecting optical fiber with the other end of the coreless optical fiber, the optical signal collected by the coreless optical fiber can be homogenized through the fusion region, reducing the angle of the optical signal collected by the coreless optical fiber, thereby reducing the loss of the signal entering the collecting optical fiber, improving the coupling efficiency between the collecting optical fiber and the optical signal, and then improving the collection rate of the optical signal.

[0091] In an exemplary embodiment, the optical signal collection system may further include a lens, an excitation light source, and an excitation optical fiber, and the method may further include:

[0092] The excitation light beam emitted by the excitation light source is collimated and coupled through a lens;

[0093] The collimated coupled excitation light beam is received by the excitation optical fiber, and the excitation light beam is transmitted to the luminescent material, so that the luminescent material emits a light signal.

[0094] As an optional implementation, the optical signal collection system may further include a photoelectric tube and a signal processor, and the above method may further include:

[0095] transmitting the optical signal through the fusion splice region to a collection optical fiber;

[0096] The optical signal is transmitted to the photoelectric tube via the collecting optical fiber;

[0097] The optical signal is converted into an electrical signal by a photoelectric tube and the electrical signal is transmitted to the signal processor.

[0098] The signal collection method is described below in combination with the optical signal collection device, luminescent material, lens, excitation light source, excitation optical fiber, photoelectric tube, signal processor, network card, and controller included in the optical signal collection system. In this embodiment, after the computer device sends a control instruction to the network card in the optical collection system, the controller can control the excitation light source to turn on, and the excitation light source can emit an excitation light beam, which is irradiated onto the lens. The lens can collimate and couple the excitation light beam so that the excitation light beam can be focused. The excitation light beam after collimation and coupling by the lens can be irradiated onto the luminescent material. Then, the luminescent material will emit an optical signal under the action of the excitation light beam. Then, the coreless optical fiber in the optical signal collection device can receive the optical signal and transmit the optical signal to the collection optical fiber through the fusion area. The collection optical fiber can transmit the optical signal to the photoelectric tube. Then, the photoelectric tube can convert the optical signal into an electrical signal and transmit it to the signal processor. Finally, the signal processor can process the electrical signal, so that the processing result is used as the detection result corresponding to the optical signal.

[0099] In this embodiment, the computer device controls the lens to collimate the excitation light beam emitted by the excitation light source, and then controls the excitation optical fiber to receive the collimated excitation light beam and transmits the excitation light beam to the luminescent material to make the luminescent material emit a light signal, thereby enabling the light signal collection device in the light signal collection system to collect the light signal, thereby realizing the collection of light signals.
