Embodiment 1
[0038] like Figure 1 to Figure 6 As shown, a kind of optical fiber probe type cleaning of the present invention, detection system, comprises spectrum analyzer 1 and circulator 4, and described spectrum analyzer 1 comprises laser 7 and spectrometer 8, and described laser 7 is the broadband light source of 1505 to 1630nm , the output optical power is 0 to 6dBm; the spectrometer 8 is a multi-port optical power analyzer, the detectable wavelength range is 1505 to 1630nm, and the detectable power range is -80dBm to 10dBm.
[0039] The circulator 4 is a three-port unidirectional ring device, the circulator 4 includes an A port, a B port and a C port, and the optical signal can only be transmitted in one direction in the circulator 4, that is, the optical signal can only be transmitted along the A port To the B port, and then transmitted from the B port to the C port, and the C port is then transmitted to the A port, and the reverse direction is isolated.

Embodiment 2
[0047] like figure 1 Described, a method for manufacturing an optical fiber probe type cleaning and detection system, comprising the following steps:
[0048] a) Connect the output end of the laser 7 to one end of the amplifier 3 to amplify the optical signal to realize the adjustable 0-300mw;
[0049] b) The A port of the circulator 4 is connected to the other end of the amplifier 3, and the B port is connected to the rear single-mode fiber 6;
[0050] c) Select a point on the single-mode optical fiber 6 in the rear section, fix it on the displacement table 9, and cut the end face of the single-mode optical fiber 6 in the rear section flat to form an optical fiber probe;
[0051] d) One end of the attenuator 2 is connected to the C port of the circulator 4, and the other end is connected to the spectrometer 8. The attenuator 2 attenuates the optical power to below the safe power of the spectrometer 8.
Embodiment 3
[0053] like Figure 1 to Figure 6 As shown, a method for using an optical fiber probe cleaning and detection system specifically includes the following steps:
[0054] Step 1: Immerse the surface to be cleaned 11 in the liquid, adjust the displacement table 9, so that the length L of the working chamber 16 is about 24-200 μm;
[0055] Step 2: Turn on the laser 1, adjust the displacement stage 9, move the fiber probe 10, and observe the interference signal on the spectrometer 8: if the interference signal is smooth, it indicates that the surface 11 to be cleaned is the clean surface; if the interference signal is not smooth, It is necessary to clean the cleaning surface 11 and fix the displacement stage 9;
[0056] Step 3: Slowly adjust the amplifier 3 to gradually increase the optical power until bubbles 12 are generated in the working cavity 16, such as Figure 4 As shown, the system enters the overall cleaning mode. The generation rate of bubbles can be controlled by adju...
