利用双凹面实现三维显示

3D Display Based on Double Concave Sides System

真三维动态显示是图像显示技术发展的一个主要目标。基于双凹面镜可观察到物体的三维实像,一项新的三维显示方案被提出:用单凹面拍摄,用双凹面实现三维显示。该方案可实现真三维动态显示,其成像光路模拟了双凹面镜成实像,显示方案具有可行性。该三维显示方案对凹面的要求:两凹面顶点间的距离是凹面曲率半径的3/2倍或1/2倍时,能在圆孔处看见三维像,看见像的角度范围分别为104.48°和138.59°。

True three-dimensional dynamic state display is a main goal of display. 3D real image of object can be observed through double concave sides system. Based on the phenomenon, a new scheme about 3D display is put forward： filming is base on one concave side and 3D display is based on double concave sides system. The scheme can achieve true three-dimensional dynamic state display. Its path of image formation rays simulates the path of rays in real image of object observed through double concave sides system. The scheme has feasibility. The concave sides in the scheme need to satisfy concrete condition： when the distance between the two apexes of concave sides is equal to 3/2 or 1/2 times of radius of curvature of the concave sides, 3D image can be seen at the sketched hole. The ranges of angle are104.48°and 138.59°.
