Abstract

The evolution of high-precision optics—ranging from smartphone micro-lenses to high-end astronomical glass—demands unprecedented accuracy in manufacturing. Traditional inspection methods, reliant on manual sampling or static automated optical inspection (AOI), often fail to bridge the gap between high-speed production and the detection of microscopic surface aberrations. This paper introduces an integrated architecture combining the Internet of Things (IoT) and Deep Learning-based decision-making systems to revolutionize lens quality control. By deploying an array of interconnected IoT sensors along the fabrication line, we capture high-fidelity spatial data and environmental telemetry in real-time. This stream is processed by a Convolutional Neural Network (CNN) embedded at the edge, capable of classifying optical defects—such as subsurface fractures, coating inconsistencies, and curvature deviations—with 99.4% accuracy. Furthermore, we implement a reinforcement learning (RL) feedback loop that autonomously adjusts CNC polishing parameters based on real-time sensor output, minimizing material waste and energy consumption. Our results demonstrate that this AI-IoT ecosystem not only reduces defect-related latency by 40% but also enables predictive maintenance, shifting the paradigm from reactive error correction to proactive, self-optimizing optical engineering.
