Description

Technical Field

[0001] The present invention relates to the field of communication technology, and in particular to an assembly and correction method and device for a small single-point laser transmitter. Background Art

[0002] The AA device (Active Alignment) can adjust the posture and relative position between the lens and the image sensor to ensure that the center of the photo is the clearest and the four corners of the picture have uniform clarity, effectively improving the consistency of camera products and ensuring the quality of the camera.

[0003] Currently, because AA equipment is relatively expensive and has high requirements for environmental configuration, small and medium-sized companies are unable to meet production needs. Due to the lack of high-precision AA (auto focus and centering) equipment for optical parameter correction, they are unable to make technical solutions to meet product calibration needs, affecting work progress. Summary of the invention

[0011] Power the collimator to emit light from inside, and power on the sensor board. Observe the collimator output software and adjust the relative position to align it with the center of the collimator cursor.

[0012] Power on the emitting diode separately and observe the collimator output software to adjust the relative position so that it is aligned with the center of the collimator cursor.

[0013] Furthermore, the action of adjusting the cursor center aligns the light source center of the transmitting module and the light source center of the receiving module with the cursor center of the parallel light tube respectively through fine adjustment.

[0014] Furthermore, the emitting diode is powered by an external power supply, and the light source center of the emitting end is aligned with the cursor center of the collimator by adjusting the current in cooperation with the XYZR micro-motion platform.

[0015] Furthermore, the fine-tuning actions are all achieved through the XYZR fine-motion platform.

[0016] Furthermore, the drawing software is CGI MAGETECHVI EW.

[0018] Collimator, used to emit standard position light source;

[0019] A structural shell, with a transmitting lens and a receiving lens on one side and a transmitting diode and a sensor component on the other side;

[0020] The power board assembly is used to provide power during the review and calibration process.
