Why Manufacturing Quality Matters: Cleanroom Photolithography vs Conventional Reflectance Targets
Last Updated: January 2025 | Reading Time: 11 minutes Introduction Two reflectance standards sit side by side on a lab bench. Both claim “50% reflectance at 905nm.” Both look identical to the naked eye—matte gray surfaces, similar size, similar price point. You pick one, calibrate your $100,000 automotive LiDAR, collect three months of validation data, […]
LiDAR Calibration Guide: How to Use Diffuse Reflectance Standards for Automotive Testing
Last Updated: January 2025 | Reading Time: 15 minutes Introduction A Tesla Model S traveling at 120 km/h on the highway relies on its LiDAR sensor to detect a stopped vehicle 200 meters ahead. The sensor must accurately measure both distance (is the obstacle 200m or 205m away?) and reflectance (is it a dark-painted car […]
