Data recovery from monolithic storage devices (MSDs) is in high demand for legal or business purposes. However, the conventional data recovery methods are destructive, complicated, and time-consuming. We develop a robotic-arm-assisted optical coherence tomography (robotic-OCT) for non-destructive inspection of MSDs, offering ~7 μm lateral resolution, ~4 μm axial resolution and an adjustable field-of-view to accommodate various MSD sizes. Using a continuous scanning strategy, robotic-OCT achieves automated volumetric imaging of a micro-SD card in ~37 seconds, significantly faster than the traditional stop-and-stare scanning that typically takes tens of minutes. We also demonstrate the robotic-OCT-guided laser ablation as a microsurgical tool for targeted area removal with precision of ±10 μm and accuracy of ~50 μm, eliminating the need to remove the entire insulating layer and operator intervention, thus greatly improving the data recovery efficiency. This work has diverse potential applications in digital forensics, failure analysis, materials testing, and quality control.

出于法律或商业目的，对从单片存储设备 (MSD) 进行数据恢复的需求很高。然而，传统的数据恢复方法具有破坏性、复杂且耗时。我们开发了一种机械臂辅助光学相干断层扫描 (robototic-OCT)，用于 MSD 的无损检测，提供约 7 μm 的横向分辨率、约 4 μm 的轴向分辨率和可调节的视场，以适应各种 MSD 尺寸。使用连续扫描策略，机器人 OCT 可在约 37 秒内实现微型 SD 卡的自动体积成像，明显快于通常需要数十分钟的传统停顿扫描。我们还展示了机器人 OCT 引导激光烧蚀作为一种显微外科工具，用于目标区域去除，精度可达 ±10 μm，准确度可达 ~50 μm，无需去除整个绝缘层和操作员干预，从而大大提高了数据质量恢复效率。这项工作在数字取证、故障分析、材料测试和质量控制方面具有多种潜在应用。
