Product Introduction

The 2π Lambertian diffuse target uses independently developed technology and processes, featuring excellent Lambertian diffuse reflection characteristics, with reflected light distributed over the inner 2π hemispherical solid angle. The target surface uses a highly stable diffuse reflection substrate, strictly following Lambert's cosine law. When the incident beam illuminates the target surface, uniform volumetric scattering occurs, and within the effective observation angle range, the radiance does not change significantly with the viewing angle, with no obvious specular reflection. As a 2π reflection reference, it is used to simulate the optical reflection response of planar targets in real-world scenarios and is a core reference target for outdoor calibration of autonomous driving, LiDAR, remote sensing, and electro-optical imaging systems. The complete set consists of a diffuse reflection target panel, aluminum alloy profile mobile stand, and universal casters, supporting rapid on-site deployment and repositioning adjustments.

 

Application Fields

Vehicle-mounted LiDAR, TOF perception system outdoor calibration for echo intensity correction, distance accuracy verification, multi-line radar perception performance testing;

Autonomous driving perception cameras, multispectral camera radiometric calibration;

Drone remote sensing, airborne electro-optical device outdoor radiometric calibration experiments;

BRDF bidirectional reflection function field testing, optical simulation physical benchmarking;

Security electro-optics, long-range electro-optical detection system performance calibration.

 

Product Advantages

Spectral Characteristics: flat spectrum, no fluorescence effect, minimal impact from polarization

Curved Surface Simulation Capability: can simulate lenses, curved workpieces, lenses, curved wafers, etc. Curved measured targets; flat white boards can only simulate planar objects;

Multi-Angle Synchronous Acquisition: can simultaneously obtain reflection data from multiple observation angles on the same target for BRDF experiments;

LiDAR Calibration Advantages: when LiDAR TOF detects curved targets, the echo reflection characteristics differ significantly from planar objects. The 2π hemisphere target is more representative of curved targets in real vehicle-mounted and industrial inspection scenarios.

Extra-Large Planar Target Surface: customizable large-diameter circular target surface to meet the outdoor calibration needs of long-distance LiDAR and vehicle perception systems
