[0031] In addition, the technical features involved in the different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0032] As Figs. 1-2 , in a first aspect, the present embodiment provides a light source performance testing device, comprising a single fiber 1 and a sleeve assembly, the sleeve assembly is used for accommodating the single fiber 1, and the sleeve assembly comprises an adjusting cylinder, a detection cylinder 4 and a second limiting part 6.

[0033] The adjusting cylinder is hollow and has the single fiber 1 built-in. In the present embodiment, the single fiber 1 comprises a standard single fiber 11 and a fixed part 12, the fixed part 12 is limited and tightened at one end of the standard single fiber 11, and the other end of the standard single fiber 11 is transmitted from the adjusting cylinder and extends into the detection cylinder 4. The adjusting cylinder is also provided with a first limiting part 5, the first limiting part 5 is used for limiting and connecting the adjusting cylinder and the single fiber 1, preferably, the first limiting part 5 can also be separated from the state of limiting the adjusting cylinder and the single fiber 1 under the action of external force, further preferably, the first limiting part 5 is detachably connected with the adjusting cylinder.

[0034] The detection cylinder 4 is also hollow, one end of which is movably connected with the adjusting cylinder along the circumferential direction of the detection cylinder 4 and is limited by the second limiting member 6 along the axial direction of the detection cylinder 4 to move relative to the adjusting cylinder, and the other end of the detection cylinder 4 is provided with an auxiliary detection part 7 protruding along the circumferential direction of the detection cylinder 4, which is disc-shaped in this embodiment, and a plurality of calibration parts 8 are distributed on the auxiliary detection part 7 along the circumferential direction of the detection cylinder 4. The positions of the calibration parts 8 on the auxiliary detection part 7 can be adjusted and distributed according to the light source test items. Preferably, the detection cylinder 4 and the auxiliary detection part 7 are integrally provided, without the need for installation and disassembly, thereby improving the assembly efficiency of the overall device. As an alternative embodiment, the two can also be separately provided and assembled by screw threads, clamping grooves and holes, etc.

[0035] The second limiting member 6 is arranged on the adjusting cylinder and connects the detection cylinder 4 and the adjusting cylinder to limit the relative movement of the two along the axial direction of the detection cylinder 4, and the projection of the second limiting member 6 along the axial direction of the detection cylinder 4 is on the auxiliary detection part 7. The detection cylinder 4 is used to rotate relative to the adjusting cylinder under the action of an external force, and specifically, the object of the external force can be the detection cylinder 4 or the adjusting cylinder. The second limiting member 6 is used to project on each calibration part 8.

[0036] The first limiting member 5 arranged on the adjusting cylinder can limit the adjusting cylinder and the single optical fiber 1, so that the two are integrated and move synchronously. Meanwhile, the second limiting part 6 is also arranged on the adjusting cylinder, which on the one hand limits the adjusting cylinder and the detection cylinder 4 only in the axial direction of the detection cylinder 4, so that the adjusting cylinder and the detection cylinder 4 can rotate relative to each other in the circumferential direction of the detection cylinder 4, and on the other hand, the second limiting part 6 can be used as a positioning member. Since the second limiting part 6 can project on the calibration parts 8 of the auxiliary detection part 7 on the detection cylinder 4 along the axial direction of the detection cylinder 4 during the relative rotation of the adjusting cylinder and the detection cylinder 4, auxiliary positioning and calibration are achieved. The experimenter can intuitively determine whether the detection cylinder 4 has been rotated to the corresponding test position relative to the adjusting cylinder according to the relative position of the second limiting part 6 and the calibration parts 8 along the axial direction of the detection cylinder 4. In this way, the problem that the experimenter cannot accurately position the corresponding test position during the test of the light source test device is effectively solved, and the accuracy of the test data is improved.

[0037] In addition, this arrangement realizes the dual-purpose function of the second limiting part, without the need for additional calibration structures, thereby reducing the number of parts and improving the utilization efficiency of the parts.

Preferably, the first limiting part 5 is a screw part, and the first through hole 31 is internally provided with a thread, and the two are threadedly connected, which is convenient for manual adjustment, and the adjustment range can be controlled by the number of turns, thereby being convenient for adjustment and avoiding damage to the single optical fiber 1.

[0042] As a transformable embodiment, the light-in part 2 and the connecting part 3 can be integrally arranged. As another transformable embodiment, the first through hole 31 can not be arranged, or be replaced by a glue containing groove or a glue filling hole, which can be filled with adhesive that can flow to the connecting part 3 and be adhesively connected with the single optical fiber 1. In addition, the first limiting part 5 can be a limiting clamp or the like structure.

[0043] Preferably, the light-in part 2 and the connecting part 3 are threadedly connected, and can be detached, which divides the adjusting cylinder into two detachable structural segments, and the single optical fiber 1 in the adjusting cylinder can be detected and installed segment by segment, thereby reducing the assembly, detection and maintenance difficulty of the single optical fiber 1 and the adjusting cylinder.

[0044] The light source performance testing device further comprises a connecting end 32 and a second through hole 33.

Further preferably, the second limiting piece 6 can abut against the bottom of the limiting fitting groove 41 to realize the circumferential limiting of the detection barrel 4.

[0047] It can be understood that the first limiting piece 5 is screw-fitted with the first through hole 31, and the second limiting piece 6 is screw-fitted with the second through hole 33, and only one of the two or neither of the two is arranged.

[0048] Preferably, the calibration part 8 is an opening along the axial direction of the detection barrel 4, and a plurality of calibration parts 8 are uniformly and spacedly distributed along the circumferential direction of the detection barrel 4. In this way, the tester can observe the second limiting piece 6 along the axial direction through the calibration part 8, thereby improving the convenience and accuracy of detection, and the uniformly and spacedly distributed calibration parts 8 correspond to uniformly divided rotation angles, thereby further improving the accuracy.

[0049] As a convertible embodiment, the calibration part 8 can also correspond to a sensor or the like for detecting the second limiting piece 6 along the axial direction of the detection barrel 4.
