A sensor spot collimation degree debugging method

Abstract

The present application belongs to the technical field of sensor, discloses a kind of sensor light spot collimation degree debugging method, comprising the following steps: S1: establish the reference corresponding relationship between the relative pose of the output signal of four-quadrant photodetector and the emission component of laser, collimating lens composition;S2: real-time acquisition four-quadrant photodetector is exported electric signal due to incident light spot position change, based on reference corresponding relationship and current electric signal, the deviation of current pose and target pose of emission component is judged;S3: according to deviation, control instruction is generated to drive actuator to adjust the pose of emission component, so that deviation reduces, until the collimation degree requirement of pre-set is satisfied.The present application can realize the automatic adjustment of the light spot position of the emission component of laser and collimating lens, thereby supporting to complete the collimation degree debugging of sensor emission light path without relying on artificial experience judgment, under the premise of ensuring debugging accuracy and repeatability, significantly improve production line debugging efficiency and product consistency.
