Technical Problem

The lack of suitable HUD stray light testing equipment in the current technology leads to the need to install the HUD in a vehicle for actual testing, which is complex, costly, time-consuming and inefficient.

Method used

A stray light testing device for automotive HUDs was designed, including a windshield fixing device, an arched light source assembly, a light source driving device, a material handling robot, and a testing robot. It can complete stray light testing without being installed in a vehicle. The light source driving device simulates light irradiation from different angles, and the testing robot captures and analyzes the projected images.

Benefits of technology

It reduces testing time and cost, improves the testing efficiency of HUD products, and enables rapid evaluation of the impact of stray light on HUD products in the laboratory.
