Abstract
A test fixture () for heads-up windshields () wherein aspherical devices () compensate for complex curvatures and optical aberrations in a heads-up display surface () of the windshield. A movable test grid () adjusts the elevation of preferred camera settings and a pivotal mounting of the test grid () enhances ghost image reduction and improves camera image resolution. A filter () limits interference of secondary ghost images (caused by IR coatings) with compliance assessment of the windshield.
