Abstract：To relieve the great requirement of public to three-dimensional display with high resolution in the fields of culture and medical treatment， we analyze and summarize the methods of the construction of three-dimensional display system with high resolution from two aspects. They are separately based on optical field reproduction and wave-front reconstruction. Seven different techniques that are acquired by making great breakthrough are described in detail. The techniques respectively include： 360 degree three-dimensional display device based on optical field reproduction， brain segmentation of Magnetic Resonance images， real-time simulation of ultrasound images based on CT data， automatic vascular centerline extraction of angiograms， non-contact real-time enhanced display of subcutaneous veins， vascular identification based on the detection of parallel structure and clustering， three-dimensional display system design and construction of high resolution dynamic wave-front reconstruction. Finally， the current limitation are reviewed and the future works are looked forward.

Key Words：3D display； High resolution； Optical field reproduction； Wave-front reconstruction； Medical images； Culture
