Background
A Head Up Display (HUD), hereinafter, is originally designed for use in piloting an aircraft. With the development of the automobile industry, the traditional manual driving can not meet the requirements of human beings, and in recent years, HUDs have also been widely applied to various automobiles. It uses the principle of optical reflection to project the important driving related information on the front windshield. The projected characters and images are adjusted on a road surface with different focal lengths of 3-10 meters, and when a driver looks forwards through the HUD, the external scenes and the data displayed by the HUD can be easily fused together. The driver does not need to look over the display and data of the instrument by lowering the head, the head-up posture is always kept, and delay and discomfort caused by neglecting the rapid change of the external environment between lowering the head and raising the head and the need of continuously adjusting the focal length of eyes are reduced.
A crucial component of the HUD device is a reflector, which is designed differently according to the HUD optics of each type of vehicle. Almost all reflectors in the industry at present are plastic parts (the common material is PC or COC), and a total reflection film layer is plated on the surfaces of the reflectors by using a vacuum coating technology after the reflectors are subjected to injection molding by a mold so as to achieve the design and use functions of products. It is known that there is a relatively fatal problem with injection-molded parts, i.e. the injection-molded product has a slight edge shrinkage due to injection-molding pressure and temperature differences, which is insignificant or even unnoticed in conventional plastic products. However, there is a strict requirement on the HUD reflector, because the edge of the reflector shrinks, and the flatness of the surface of the reflector is not good, the surface with poor flatness will generate distortion, and blur when reflecting the image, and this phenomenon is unacceptable when the automobile is driven, which not only affects the transmission of information, but also may cause traffic accidents due to misjudgment of the driver.
However, the shrinkage of the reflector can be recognized by naked eyes only by repeatedly checking the shrinkage under reflection, the difficulty in checking the whole reflector is high, misjudgment or missed judgment can be caused when each detection environment is different or even when people are different, and great trouble is brought to the inspection of reflector products. How to effectively and rapidly detect shrinkage of the edge of the reflector becomes a great problem to be solved at present.
