[0002] A Raman fiber optic probe is a sensor based on Raman spectroscopy, used for non-destructive and non-contact analysis and detection of substances. It consists of a laser beam generated by a laser, transmitted through an optical fiber to the sample surface. The sample surface generates Raman scattered light signals, which are received by the probe, converted into electrical signals by a photoelectric converter, and finally analyzed by a signal processing device to obtain the Raman spectral information of the sample. Raman fiber optic probes are widely used in biomedicine, food safety, environmental monitoring, and chemical reaction processes, becoming an indispensable tool in analytical testing.

[0028] The standard substance 3 is polystyrene.

[0029] The outer side of the housing 101 is also provided with a control interface 8, which can be connected to an external power source to power the automatic calibration equipment for the fiber optic probe.

[0030] The adjustment mechanism also includes an energy adjustment module, which is located below the support frame 102 and can control the working state of the energy detection circuit board 4.

[0031] The energy regulation module includes a power supply module for the energy detection circuit board and a control module.

[0032] The working principle of the automatic calibration device for fiber optic probes described in this embodiment is as follows: In the initial state, after the fiber optic probe of the Raman device is replaced, it is inserted into the interface 2 of the automatic calibration device. The horizontal movement motor 5 adjusts its horizontal position so that the standard material 3 on the rotating arm 603 is aligned with the interface 2 for wavelength detection and calibration. After the wavelength is calibrated, the horizontal movement motor 5 adjusts its position to drive the rack 604. The rack 604 drives the rotating gear 602 and the rotating shaft 601. The rotating arm 603 rotates counterclockwise by 90° with the rotating shaft 601. At the same time, the horizontal movement motor 5 also drives the energy detection circuit board 4 to the position of the interface 2 for energy detection and calibration.

[0033] Example 2

[0034] like Figure 2As shown, an automatic calibration device for a fiber optic probe includes a support mechanism, a docking interface 2, a standard substance 3, an energy detection circuit board 4, and an adjustment mechanism. The support mechanism includes a housing 101, a support frame 102, and a standard substance support 103. The docking interface 2 is located on the upper outer side of the housing 101. The adjustment mechanism includes a transverse moving motor 5 and an axial pushing mechanism. The support frame 102 is located inside the housing 101, and the transverse moving motor 5 is installed inside the support frame 102.

[0040] The working principle of the automatic calibration device for fiber optic probes described in this embodiment is as follows: After the fiber optic probe of the Raman device is replaced, it is inserted into the interface 2 of the automatic calibration device. At this time, the lateral movement motor 5 will move laterally, driving the internal support frame 102 to move, so that the standard material 3 is aligned with the interface 2. After the lateral position is confirmed, the drive motor 701 in the axial drive mechanism works, and through the drive screw 702, it drives the drive rod 703 to push the standard material holder 103 to adjust the axial position of the standard material 3. The Raman device outputs Raman light, which is transmitted through the fiber optic probe to the standard material 3 on the standard material holder 103. Then, the wavelength is calibrated by detecting the reflected light. After the wavelength is calibrated, the lateral movement motor 5 adjusts the lateral position of the support frame 102 again, so that the energy detection circuit board 4 is aligned with the interface 2, and the energy of the Raman light is detected to calibrate its energy.
