Lambertian vs Specular vs Retroreflective Targets — Which Do You Need? (2026)
Three fundamentally different reflection modes — Lambertian (diffuse), specular (mirror), and retroreflective (back-toward-source) — define optical and LiDAR test targets. Lambertian is the standard for reproducible measurement. This guide explains the physics behind each, when to use them, and how to verify your target actually behaves the way it should.
How to Test LiDAR Performance with Reflectance Targets (2026 Lab Setup Guide)
A complete LiDAR performance test characterizes detection range, range accuracy, and intensity calibration using calibrated reflectance targets in a controlled lab environment. This step-by-step guide walks through equipment requirements, environmental controls, the three core test protocols, common mistakes that invalidate results, and the documentation needed for OEM-defensible test reports.
10%, 50%, 90% Reflectance Targets — Which Do You Need? (2026)
The industry-standard reflectance values for LiDAR testing are 10%, 50%, and 90% — each one tests a different sensor behavior. The 10% target stress-tests detection range; the 50% target characterizes typical performance; the 90% target verifies saturation behavior. This guide explains when to use each, and when custom values matter.
