Description

Technical Field

[0001] This utility model relates to the field of optical technology, and in particular to an optical fiber system and a non-invasive arteriosclerosis early warning device. Background Technology

[0002] Currently, early screening and diagnosis of arteriosclerosis mainly rely on non-invasive blood pressure measurement, ultrasound detection, and pulse wave velocity (PWV) analysis. Traditional non-invasive detection methods (such as cuff blood pressure measurement) have low accuracy in acquiring pulse wave signals, making it difficult to meet the needs of high-resolution vascular elasticity measurement. Ultrasound and other imaging methods are limited by sampling rate and signal processing, making it difficult to achieve high temporal resolution real-time monitoring of arterial hemodynamics.

[0003] In summary, most existing methods require direct contact with the skin and are greatly affected by individual differences (such as skin thickness and blood vessel depth), which may affect measurement stability and repeatability. Furthermore, existing measurement devices are usually large, expensive, difficult to operate, and difficult to measure accurately, making them difficult to popularize in primary healthcare or home testing environments.

[0039] Figure 1 This is a schematic diagram of the structure of an optical fiber system provided in an embodiment of this utility model, for reference. Figure 1The fiber optic system 100 includes: a fiber optic array 110, a first fiber optic assembly 120, and a second fiber optic assembly 130; the fiber optic array 110 includes a first fiber 111, a second fiber 112, a third fiber 113, a fourth fiber 114, and a fifth fiber 115; the first end of the first fiber 111 is connected to an infrared laser A for generating a first measurement beam, and the second end of the first fiber 111 is connected to a first measurement beam receiving end of a silicon photonics chip B for receiving the first measurement beam; the second measurement beam transmitting end of the silicon photonics chip B for emitting a second measurement beam is connected to the first end of the second fiber 112, and the second end of the second fiber 112 is connected to the first fiber optic assembly 120; the third measurement beam transmitting end of the silicon photonics chip B for emitting a third measurement beam is connected to the first fiber optic assembly 130. The first end of the third optical fiber 113 is connected to the first optical fiber assembly 120, and the second end of the third optical fiber 113 is connected to the second optical fiber assembly 130; the first signal light output end of the red laser C is connected to the first optical fiber assembly 120, and the second signal light output end of the red laser C is connected to the second optical fiber assembly 130; the first optical fiber assembly 120 and the second optical fiber assembly 130 are also connected to the optical lens D; the first end of the fourth optical fiber 114 is connected to the first coupling end of the silicon photonics chip B for receiving the second measurement beam and the first signal light, and the second end of the fourth optical fiber 114 is connected to the first optical fiber assembly 120; the first end of the fifth optical fiber 115 is connected to the second coupling end of the silicon photonics chip B for receiving the third measurement beam and the second signal light, and the second end of the fifth optical fiber 115 is connected to the second optical fiber assembly 130.

Infrared laser A generates a first measurement beam, which is input to the silicon photonics chip B from the first measurement beam receiving end via the first fiber optic cable 111. The second measurement beam emitted by the second measurement beam transmitting end of the silicon photonics chip B enters the first fiber optic assembly 120 via the second fiber optic cable 112. The third measurement beam emitted by the third measurement beam transmitting end of the silicon photonics chip B enters the second fiber optic assembly 130 via the third fiber optic cable 113. The first signal light generated by red laser C is emitted from the first signal light output end into the first fiber optic assembly 120, and the second signal light generated by red laser C is emitted from the second signal light output end into the second fiber optic assembly 130. The second measurement beam, the first signal light, the third measurement beam, and the second signal light are re-received after exiting through the optical lens D.

The third measurement beam and the second signal beam pass through the second optical fiber assembly 130 again, and finally enter the second coupling end of the silicon photonic chip B through the fifth optical fiber 115, and couple back to the silicon photonic chip B.

[0041] It is understood that in this embodiment of the invention, in addition to the silicon photonic chip B, a first optical fiber assembly 120 and a second optical fiber assembly 130 are provided because if only the silicon photonic chip B is used in the optical fiber system 100, the silicon photonic chip B needs to be perfectly coupled to the optical lens D, and the positioning scheme needs to be redesigned. This embodiment of the invention, by providing the first optical fiber assembly 120 and the second optical fiber assembly 130, allows for pluggable connection between the optical fiber system 100 and the optical lens D, facilitating user operation.

[0042] This embodiment of the invention enables the coaxial transmission and reception of the measurement beam and the signal beam by setting two optical fiber components, which is low in cost and can ensure measurement accuracy.

[0043] Figure 2 This is a schematic diagram of another optical fiber system provided by an embodiment of the present invention. Optionally, based on the above embodiments, refer to... Figure 2 The first fiber optic assembly 120 includes a first circulator 121 and a first coupler 122; the second fiber optic assembly 130 includes a second circulator 131 and a second coupler 132; the first end of the first circulator 121 is connected to the second measurement beam transmitting end, the second end of the first circulator 121 is connected to the first end of the first coupler 122, and the second end of the first coupler 122 is connected to the optical lens D; the first end of the second circulator 131 is connected to the third measurement beam transmitting end, the second end of the second circulator 131 is connected to the first end of the second coupler 132, and the second end of the second coupler 132 is connected to the optical lens D; the third end of the first circulator 121 is connected to the first coupling end, the first signal light output end of the red laser C is connected to the third end of the first coupler 122; the third end of the second circulator 131 is connected to the second coupling end, and the second signal light output end of the red laser C is connected to the third end of the second coupler 132.

[0044] It should be noted that infrared laser A generates a first measurement beam, which is input to silicon photonics chip B from the first measurement beam receiving end via the first optical fiber 111. The second measurement beam emitted from the second measurement beam transmitting end of silicon photonics chip B enters the first circulator 121 via the second optical fiber 112 and then enters the first coupler 122. The third measurement beam emitted from the third measurement beam transmitting end of silicon photonics chip B enters the second circulator 131 via the third optical fiber 113 and then enters the second coupler 132. The first signal light generated by red laser C is emitted from the first signal light output end into the first coupler 122, and the second signal light generated by red laser C is emitted from the second signal light output end into the second coupler 132. The second measurement beam, the first signal light, the third measurement beam, and the second signal light are re-received after exiting through optical lens D. The second measurement beam and the first signal light, after passing through the first coupler 122, enter the first circulator 121 and finally enter the first coupling end of silicon photonics chip B via the fourth optical fiber 114, coupling back to silicon photonics chip B. After passing through the second coupler 132, the third measurement beam and the second signal beam enter the second circulator 131, and finally enter the second coupling end of the silicon photonic chip B through the fifth optical fiber 115, and couple back to the silicon photonic chip B.

[0045] Figure 3 This is a schematic diagram of another optical fiber system provided by an embodiment of the present invention. Optionally, based on the above embodiments, refer to... Figure 3 The first fiber optic assembly 120 includes a first circulator 121 and a first coupler 122; the second fiber optic assembly 130 includes a second circulator 131 and a second coupler 132; the first end of the first coupler 122 is connected to the second measurement beam transmitting end, the second end of the first coupler 122 is connected to the first end of the first circulator 121, and the second end of the first circulator 121 is connected to the optical lens D; the first end of the second coupler 132 is connected to the third measurement beam transmitting end, the second end of the second coupler 132 is connected to the first end of the second circulator 131, and the second end of the second circulator 131 is connected to the optical lens D; the third end of the first circulator 121 is connected to the first coupling end, the first signal light output end of the red laser C is connected to the third end of the first coupler 122; the third end of the second circulator 131 is connected to the second coupling end, and the second signal light output end of the red laser C is connected to the third end of the second coupler 132.

[0046] It should be noted that infrared laser A generates a first measurement beam, which is input to silicon photonics chip B from the first measurement beam receiving end via the first optical fiber 111. The second measurement beam emitted from the second measurement beam transmitting end of silicon photonics chip B enters the first coupler 122 via the second optical fiber 112 and then enters the first circulator 121. The third measurement beam emitted from the third measurement beam transmitting end of silicon photonics chip B enters the second coupler 132 via the third optical fiber 113 and then enters the second circulator 131. The first signal light generated by red laser C is emitted from the first signal light output end into the first coupler 122, and the second signal light generated by red laser C is emitted from the second signal light output end into the second coupler 132. The second measurement beam, the first signal light, the third measurement beam, and the second signal light are re-received after exiting through optical lens D. The second measurement beam and the first signal light pass through and enter the first coupling end of silicon photonics chip B via the fourth optical fiber 114, and are coupled back to silicon photonics chip B. The third measurement beam and the second signal beam pass through the second coupler 132 and enter the second coupling end of the silicon photonic chip B through the fifth optical fiber 115, and are coupled back to the silicon photonic chip B.

[0047] It is understood that in this embodiment of the invention, the order of the circulator and the coupler is not fixed, and the same function can still be achieved by swapping their positions.

[0048] Optionally, based on the above embodiments, the splitting ratio of the first end and the third end of the first coupler 122 is 90:10, and the splitting ratio of the first end and the third end of the second coupler 132 is 90:10.

[0049] It should be noted that the splitting ratios of the first and third ends of the first coupler 122 and the first and third ends of the second coupler 132 are not fixed. The same function can be achieved by using other splitting ratios. However, the power of the measurement beam and the signal beam in the output beam of the optical lens D will change. Couplers with other splitting ratios can be selected without affecting the signal-to-noise ratio.

[0050] Optionally, based on the above embodiments, continue to refer to... Figure 2 and Figure 3 The fiber optic system 100 also includes an adapter 140; the first fiber optic assembly 120 and the second fiber optic assembly 130 are both connected to the optical lens D via the adapter 140.

[0051] The adapter 140 has two female ports.

[0052] In this embodiment of the invention, by providing an adapter 140, the fiber optic cable of the optical lens D can be easily disassembled, improving operational flexibility.

[0053] Optionally, based on the above embodiments, all optical fibers in the fiber array 110 are polarization-maintaining fibers, and all devices in the first fiber assembly 120 and the second fiber assembly 130 are polarization-maintaining devices.

[0054] It should be noted that in the embodiments of this utility model, the optical fiber part uses a fully polarization-maintaining device. This is because, under non-polarization-maintaining conditions, slight external disturbances will change the polarization state of the beam transmitted in the optical fiber. Only light with the same polarization state can interfere. Changes in the polarization state of the beam will cause uncertain changes in the interference result, making the measurement result unpredictable. If it can be ensured that all optical fiber devices remain fixed during the measurement, a non-polarization-maintaining device can also be selected.

[0055] In this embodiment of the present invention, all optical fibers in the fiber array 110 are polarization-maintaining fibers, and all devices in the first fiber assembly 120 and the second fiber assembly 130 are polarization-maintaining devices, which can ensure the stability of the beam polarization state, thereby optimizing the performance and reliability of the fiber system 100.

[0056] Optionally, based on the above embodiments, all devices of the optical fiber system 100 are connected via polarization-maintaining optical fibers.

[0057] In this embodiment of the invention, all components of the fiber optic system 100 are connected through polarization-maintaining fibers, which further ensures the stability of the beam polarization state, thereby further optimizing the performance and reliability of the fiber optic system 100.

[0058] In summary, the fiber optic system 100 provided by this embodiment of the invention, by setting two fiber optic components, can meet the coaxial transmission and reception of the measurement beam and the signal beam, with low cost and guaranteed measurement accuracy. The adapter 140 allows for easy disassembly and removal of the pigtail of the optical lens D, improving operational flexibility. All fibers in the fiber optic array 110 are polarization-maintaining fibers, and the devices in the first fiber optic component 120 and the second fiber optic component 130 are all polarization-maintaining devices, ensuring the stability of the beam polarization state, thereby optimizing the performance and reliability of the fiber optic system 100. The fact that all devices in the fiber optic system 100 are connected via polarization-maintaining fibers further ensures the stability of the beam polarization state, thereby further optimizing the performance and reliability of the fiber optic system 100.

During measurement, the user fixes the optical lens D to the top of the lens holder using a clamp, adjusts it above the measurement point (such as the carotid artery or femoral artery), and uses the red laser C to indicate the measurement position. After the system starts, optical displacement detection begins.
