Embodiment
As shown in Figure 1, the system is made up of five big parts：
2.8 cun of high brightness LCD displays：This is the signal source of the system, is a video terminal device.By various videos
Signal distinguishes input terminal display as required.The picture signal of high brightness and high resolution degree thus has been obtained, it is defeated by light path
Enter to transparency reflector.
The transparency reflector mechanism of transparency reflector and photochopper composition：This is the critical component of HUD systems, is a kind of saturating
Bright high index of refraction（Plated film）Spherical acrylic material（Lucite）Form, manufactured using advanced pressure injection technique, due to
It contains oxide Ti and Si composition, and its refractive index is between 1.8 ~ 2.2, more than the refractive index of common acrylic material 1.5,
So surface reflectivity increases many, then it can be just imaged a long way off by the interference of multiple light, due to the reflective operation of spherical
The setting in face, original image signal will be amplified, in the case where focusing on correct adjustment, the amplification quantity of image is up to 5 times of left sides
The right side, thus the image being clearly exaggerated being above presented in human pilot.Compared with prior art, focusing system is more
