3D Virtual Digital Television HMD System Design And Manufacture

With the development of science and technology, the Plane Display Technique got rapid development with each passing day. But the display effect couldn't get out the fate of "plane" with these plane display devices. So Digital TV terminal possessing 3D display technique is sure to become the important aim and kernel in the development of display technique in the future. And it is the rapid development of 3D virtual HMD system that brings great chances to realize Digital TV 3D virtual system all over the world and china.In this paper the HMD system used in 3D virtual Digital TV is developed, the human's factors and images of HMD are analyzed. The original configuration, optimization design and tolerance analysis of the optical system in HMD system are finished by ZEMAX. A 3D virtual HMD system of visual optical wavelength is designed. As the system has been designed in paper, the MTF of this system is more than 0.32 in 301p/mm, The distortion is less than 5 percent, The radius of lateral color is less than 20μm, F/# is less than 3, the total length of system is less than 70mm, and the total weight is about 157g.
