Description

Technical Field

[0001] This utility model belongs to the technical field of automotive windshield inspection, and specifically discloses an optical inspection and judgment device for automotive windshields. Background Technology

[0002] The windshield of a car is a crucial safety component, and its optical performance is among the most important. The testing of four optical properties—light transmittance, optical distortion, secondary image deviation, and color recognition—is particularly important. Optical distortion occurs because unevenness or localized optical inhomogeneities on the glass surface cause light rays to deviate, resulting in image distortion. Significant optical distortion can easily cause driver eye fatigue, leading to traffic accidents. Glass optical distortion testing typically uses a projection system. A slide projector projects an array of patterns onto a screen through the glass panel under test, and the distortion of the pattern on the screen is assessed by visually observing the changes in the pattern. However, this testing requires a darkroom to accurately identify the distortion on the screen, and operating instruments and adjusting the glass in a darkroom presents significant inconveniences.
