True Test HUD Head-up Display Test Module

Head-up displays (HUDs) pose unique measurement challenges for manufacturers, who must account for projected image luminance, contrast, and clarity regardless of ambient conditions, virtual image positions, or focal distances on an infinite viewing plane. Comprehensive HUD testing requires both photometric (light data) and dimensional (spatial data) measurement combined to ensure the accuracy of information conveyed to a vehicle operator within a rapidly changing, real-world environment. Radiant’s TT-HUD application module can be used with our 200 mm electronically controlled lens to evaluate properties of light (brightness, contrast) as well as spatial measurements used to evaluate projection quality (distortion, warping) against defined tolerances.
