For 3D images produced by the two former V3D imaging systems are unclarity,a high resolution,passive rotating sweep V3D imaging system based on digital micro-mirror device and double helically-curved screen is put forward and realized.
针对前两代体三维(V3D)成像系统存在图像轮廓不够清晰问题,提出并实现了一种基于空间光调制器和双螺旋投影面的被动式旋转体扫描三维(RSV3D)成像系统。
3) rotate scanning
旋转扫描

The new display screen which is based on the principle of mechanic rotate scanning is designed.
依据机械转动旋转扫描的显示原理,提出了一种新型显示屏的设计方案。
4) Rotated scanning
旋转扫描
1.
Simulation results show that comparing with long-side scanning,short-side scanning and sub-area scanning,the rotated scanning of rectangular part can greatly decrease temperature gradient in the begin point and the end point of the first scanning line,especially there is a positive temperature gradient in the end point which can avoid the temperature decreasing of the molten metal.
试验发现,长边、短边及分区扫描下起始边起点和终点均存在较大的温度梯度,旋转扫描不仅能有效降低起始点温度下降程度,而且终点还存在正的温度梯度,避免了起始边温度迅速下降;成形件旋转与反向扫描相结合较大地改善了成形件内部的温度分布均匀程度,降低了成形件由于热应力而产生的翘曲变形。
5) rotary scanning
旋转式扫描
6) rotating trace
旋转扫描线

CAS号:
性质:将图像(或分子)绕一定轴线转动一定角度后能使图像复原的一类对称动作。旋转据以进行的轴线称作旋转轴,使图像绕轴后复原的最小转角称作基转角α。设α=2π/n,显然,旋转角为α整数倍的角度均能使图像复原,不难论证,在2π角度范围内独立、不等同旋转对称动作的种数为n。
