s10, turning on the light source 110 to form an output light path.
Before the optical path is adjusted, the laser is installed on the optical platform, the height and the emitting direction of the laser are adjusted according to the requirement, and then the laser is turned on as the light source 110 to form an output optical path. The light source 110 is a spatial light collimation output, so as to ensure the control of the light height of the light source 110 in the light path adjustment process. In the actual operation process, the light height of the light source 110 can be adjusted to 123mm, and the power of the light source 110 can be adjusted to about 2 mW.
It should be noted that, when the optical path is adjusted, the human eye is not on the same horizontal plane as the laser light source 110, and the laser protection glasses should be worn to prevent the laser light source 110 from causing irreversible damage to the human eye.
S20, the first diaphragm component of the optical path adjusting system 100 is disposed on the output optical path of the light source 110.
S30, adjusting the height of the first diaphragm 140 in the first diaphragm assembly through the third adjusting mechanism of the first diaphragm assembly, so that the output light path of the light source 110 passes through the first light transmitting hole of the first diaphragm 140.
The first light hole is formed in the first diaphragm 140, the first diaphragm 140 is placed on the output light path of the light source 110, and the height of the first diaphragm 140 and the size of the first light hole are adjusted through the third adjusting mechanism, so that the output light path of the light source 110 just passes through the first light hole, and at the moment, the height of the first light hole of the first diaphragm 140 is equal to the light height of the light source 110.
S40, moving the first diaphragm assembly to a first position between the mirror adjustment device 120 and the optical fiber adjustment device 130 of the optical path adjustment system 100.
After the height of the first diaphragm 140 and the size of the first light-transmitting hole are adjusted, the first diaphragm 140 is moved to a first position between the mirror adjustment device 120 and the optical fiber adjustment device 130, so as to adjust the height of the mirror adjustment device 120.
S50, the position of the reflecting mirror 121 in the reflecting mirror adjusting device 120 is adjusted by the first adjusting mechanism 122 of the reflecting mirror adjusting device 120, so that the reflected light of the reflecting mirror 121 passes through the first light transmitting hole of the first diaphragm 140.
After the first diaphragm 140 is placed on the reflection light path of the reflector adjusting device 120, the first adjusting piece 1224 in the first adjusting mechanism 122 is adjusted to adjust the heights of the adjusting frame 1223 and the reflector 121 in the reflector adjusting device 120, so that the output light path of the light source 110 passes through the first light transmission hole of the first diaphragm 140 after being reflected by the reflector 121, and at this time, the reflection light path of the reflector 121 is equal to the light height of the output light path of the light source 110, that is, the position of the reflector 121 is determined.
Before adjusting the optical path, the mirror adjusting device 120 is assembled, and the mirror adjusting device 120 includes a mirror 121, an adjusting frame 1223, an optical extension rod 1222, and an extension rod bracket 1221. When in assembly, the extension rod support 1221 is arranged on the optical platform, one end of the optical extension rod 1222 is connected with the extension rod support 1221, the other end is connected with the adjusting frame 1223, and the reflecting mirror 121 is arranged on the adjusting frame 1223; wherein the rod support 1221 is capable of rotating on the optical platform, and the height of the optical rod 1222 relative to the optical platform is also capable of being adjusted accordingly.
After the light source 110 is turned on to form an output light path, the angle of the rod support 1221 and the position of the optical rod 1222 relative to the optical platform need to be adjusted according to the position of the output light path, so that the light spot of the light source 110 is located in the middle area of the reflector 121, and the output light path of the light source 110 is perpendicular to the reflection light path of the reflector 121. That is, the laser light source 110 is incident on the mirror 121 at an incident angle of 45 °, and then the mirror 121 is reflected at a reflection angle of 45 °. This step is provided to facilitate adjustment of the optical path and to facilitate subsequent writing of the optical fiber 200.
S60, the optical fiber 200 is mounted on the optical fiber clamping assembly 131 of the optical fiber adjusting device 130.
The fiber optic adjustment device 130 is assembled prior to installation of the fiber 200 on the fiber clamping assembly 131. Fiber optic adjustment device 130 includes a clamp, a lifting slide 1321a, and a sloped platform 1321b. During assembly, lifting slide 1321a is mounted on the optical platform, tilting platform 1321b is mounted on lifting slide 1321a, and clamping members are mounted on tilting platform 1321b, so that the height, inclination and angle of optical fiber clamping assembly 131 can be adjusted by adjusting lifting slide 1321a and tilting platform 1321b, thereby adjusting the position of optical fiber 200.
After the fiber optic adjustment device 130 is assembled, the optical fiber 200 is mounted on the fiber clamping assembly 131. The fiber clamping assembly 131 includes a first clamping portion 1311 and a second clamping portion 1312 disposed at intervals along a first direction, with the optical fiber 200 clamped between the first clamping portion 1311 and the second clamping portion 1312. Before fixing, removing a coating layer at the middle position of the optical fiber 200 by using a blade or a wire stripper, and wiping the bare fiber clean by using alcohol; the optical fiber 200 is then secured between the first clamp 1311 and the second clamp 1312 with a slight tension, wherein the bare fiber length is 10cm.
S70, the height of the optical fiber clamping assembly 131 is adjusted through the second adjusting mechanism 132 of the optical fiber adjusting device 130, so that the optical fiber 200 bisects the reflected light of the reflecting mirror 121.
When the optical path is adjusted, it is necessary to ensure the level of the optical fiber 200 in the extending direction, that is, to ensure that the portion of the optical fiber 200 clamped between the two clamping portions remains level with respect to the optical platform. Since the optical fiber 200 is under tension, when a section is held horizontally with respect to the optical bench, it is indicated that the portion between the clamping members is held horizontally with respect to the optical bench.
After the positions of the first diaphragm 140 and the mirror 121 are adjusted, the reflected light of the mirror 121 passes through the first light transmission hole of the first diaphragm 140 and then strikes the first region between the first clamping portion 1311 and the second clamping portion 1312. The height of the optical fiber clamping assembly 131 is adjusted by the second adjusting mechanism 132 of the optical fiber adjusting device 130 so that the reflected light of the mirror 121 passes through the optical fiber 200 between the first clamping portion 1311 and the second clamping portion 1312.
It should be noted that, the monitoring device 160 is disposed at a side of the optical fiber adjusting device 130 away from the mirror adjusting device 120, and the monitoring device 160 changes along with the change of the angle of the reflected light of the mirror 121, so that the monitoring device 160 can receive the reflected light of the mirror 121 and output the reflected light image to determine whether the reflected light of the mirror 121 is bisected by the optical fiber 200.
If the reflected light is divided equally by the optical fiber 200, the position of the optical fiber 200 is the target position at this time, and no adjustment is required; if the reflected light is not divided by the optical fiber 200, the third adjusting member 1322 in the second adjusting mechanism 132 is adjusted according to the reflected light image output by the monitoring device 160, so as to adjust the overall height of the optical fiber 200 until the reflected light is divided by the optical fiber 200 at the corresponding position.
And S80, moving the first diaphragm assembly to a second position along the length direction of the optical fiber 200.
After the adjustment of the height of the optical fiber 200 corresponding to the first position is completed, the first diaphragm 140 in the first diaphragm assembly needs to be moved to the second position, so that the height level of the optical fiber 200 between the first position and the second position is ensured, thereby ensuring the height level of the optical fiber 200 between the first clamping portion 1311 and the second clamping portion 1312.
S90, the position of the reflecting mirror 121 is adjusted by the first adjusting mechanism 122, so that the reflected light of the reflecting mirror 121 passes through the first light transmitting hole of the first diaphragm 140.
After the first diaphragm 140 is placed at the second position, the second adjusting member 1225 in the first adjusting mechanism 122 is adjusted to adjust the angle of the adjusting frame 1223 and the mirror 121 in the mirror adjusting device 120, so that the output light path of the light source 110 passes through the first light hole of the first diaphragm 140 after being reflected by the mirror 121. Meanwhile, the first diaphragm 140 can also monitor the light height of the reflected light, and if the reflected light of the reflecting mirror 121 cannot pass through the first light hole, the light height of the reflected light can be adjusted in time.
S100, the second adjusting mechanism 132 adjusts the height difference between the first clamping part 1311 and the second clamping part 1312 of the optical fiber clamping assembly 131, so that the optical fiber 200 bisects the reflected light of the reflecting mirror 121.
After the positions of the first diaphragm 140 and the mirror 121 are adjusted, the reflected light of the mirror 121 passes through the first light transmission hole of the first diaphragm 140 and then strikes the second region between the first clamping portion 1311 and the second clamping portion 1312. The reflected light of the mirror 121 is passed through the optical fiber 200 between the respective first clamping portion 1311 and second clamping portion 1312 by adjusting the height difference of the first clamping portion 1311 and second clamping portion 1312 by adjusting the fourth adjusting piece 1323 of the second adjusting mechanism 132.
The monitoring device 160 is moved to the corresponding reflected light path, and the monitoring device 160 receives the reflected light of the reflecting mirror 121 and outputs a reflected light image to determine whether the reflected light of the reflecting mirror 121 is divided by the optical fiber 200.
If the reflected light is divided equally by the optical fiber 200, the position of the optical fiber 200 is the target position at this time, and no adjustment is required; if the reflected light is not divided by the optical fiber 200, the fourth adjusting member 1323 in the second adjusting mechanism 132 is adjusted according to the reflected light image output by the monitoring device 160, so as to adjust the height difference between the first clamping portion 1311 and the second clamping portion 1312 until the reflected light is divided by the optical fiber 200 at the corresponding position.
Optionally, after the heights of the two positions of the optical fiber 200 are adjusted, to ensure the consistency of the overall height of the optical fiber 200, the adjustment result needs to be detected, which mainly includes the following contents:
the first diaphragm assembly is moved to the first position, the position of the reflecting mirror 121 is adjusted by the first adjusting mechanism 122, the reflected light of the reflecting mirror 121 passes through the first light transmitting hole of the first diaphragm 140, and then the monitoring device 160 is used to detect whether the optical fiber 200 bisects the reflected light of the reflecting mirror 121.
If the optical fiber 200 bisects the reflected light of the reflecting mirror 121, it is determined that the optical fiber 200 is at the target position at this time, and no adjustment is required; if the optical fiber 200 does not bisect the reflected light of the mirror 121, the second adjusting mechanism 132 continues to adjust the height difference between the first clamping portion 1311 and the second clamping portion 1312 until the optical fiber 200 bisects the reflected light of the mirror 121.
When adjusting the height level of the optical fiber 200 relative to the optical platform, the first diaphragm 140 needs to be repeatedly replaced between the first position and the second position, and the height level of the optical fiber 200 is stopped when the optical fiber 200 is bisected by the reflected light of the mirror 121 without any adjustment until the optical fiber is replaced to one of the positions.
Optionally, in the embodiment of the present application, when the optical path is adjusted, a second diaphragm 150 can be placed at each of the first position and the second position, without changing the position of the first diaphragm 140 multiple times, so that the influence of the repeated movement of the first diaphragm 140 on the detection effect of the reflected light on the optical height is avoided, and the accuracy of the optical path adjustment is improved.
Optionally, the optical path adjusting method in the embodiment of the present application further includes the following steps:

The first diaphragm assembly is moved onto the reflection light path of the mirror 121, so that the reflection light of the mirror 121 passes through the first light transmission hole of the first diaphragm 140. I.e. the first diaphragm 140 is positioned in the reflected light path at a reflection angle of 12045 deg. of the mirror adjustment means to facilitate vertical adjustment of the optical fiber 200 with respect to the reflected light path.
Then, the angle between the length direction of the optical fiber 200 and the reflected light path of the reflecting mirror 121 is adjusted by the second adjusting mechanism 132, so that the reflected light of the reflecting mirror 121 passes through the first light transmitting hole of the first diaphragm 140 after being reflected by the optical fiber 200. In the practical use process, when the height of the optical fiber 200 relative to the optical platform is adjusted, the optical fiber 200 can only be ensured to be parallel to the optical platform, but the angle of the optical fiber 200 in the horizontal direction cannot be ensured, and if the angle of the optical fiber 200 deviates, the subsequent writing process of the optical fiber 200 is not facilitated. Even leading to failure of writing.
The fifth adjusting element 1324 of the optical fiber adjusting device 130 is adjusted to rotate the optical fiber 200 in the horizontal direction until the reflected light of the reflecting mirror 121 passes through the first diaphragm 140 again after being reflected by the optical fiber 200, that is, the incident light path of the optical fiber 200 coincides with the reflected light path, thereby realizing the vertical adjustment of the optical fiber 200 and the reflected light path, and facilitating the writing of the subsequent optical fiber 200.
