Abstract: In modern aviation, effective maintenance is crucial for ensuring aircraft safety and performance. Inspecting internal components within aircraft panels poses significant challenges, often requiring specialized tools like borescopes. This project aims to develop a LiDAR-based prototype scanner to generate high-resolution 3D images of internal structures, providing engineers with a comprehensive view for maintenance inspections. The system utilizes LiDAR (Light Detection and Ranging) technology to capture depth data, which is processed to create detailed 3D models that enable the identification of issues such as misalignment's, cracks, or missing components. A micro controller, such as an Arduino Uno, interfaces with the LiDAR sensor to collect data, which is then transmitted to a laptop for visualization and analysis. This non-invasive approach offers a quick and accurate alternative to traditional inspection methods, reducing reliance on manual borescopic techniques. While the current version serves as a proof of concept, future enhancements could include industrial-grade LiDAR sensors and automated inspection systems to meet stringent aviation safety standards. Ultimately, this project seeks to demonstrate the potential of LiDAR technology to improve the efficiency and accuracy of aircraft maintenance workflows.
