Reinforcement learning for lens-alignment equipment

Fujikura reported 14.5-second lens alignment with reinforcement learning

WorkingCompany's own claimOfficial ↗

Problem

Conventional automatic lens alignment sometimes missed product specifications and required manual correction. Training a controller directly on production equipment risked disruption and equipment wear.

Approach

Fujikura trained a reinforcement-learning controller in a simulator and transferred it to manufacturing equipment. Engineers used numerical features extracted from beam images to reduce sensitivity to visual noise. The company reported completed deployment and ongoing maintenance.

Results

14.5 secondsaverage alignment time in actual-equipment experiments, versus 57.9 seconds manually and 26.3 seconds with conventional automation, per FujikuraCompany's own claim[1]

Takeaway

Extracting beam features helped the controller cope with differences between simulated and real images. The timing figures came from equipment experiments, rather than a factory-wide productivity measurement.
