概括
一个新的PET100校准幻影提高了光学表面监测系统 (VOXELAN) 的准确性和稳定性. 这种增强的幻影,结合新的放置程序,最大限度地减少了设置错误,以精确地进行坐标校准.
科学领域:
- 光学计量学是指光学计量学.
- 表面监测系统的表面监测系统
- 校准技术是指校准技术的使用.
背景情况:
- 目前基于光截面的光学表面监测系统 (VOXELAN) 的校准幻影使用像Derlin这样的材料,这些材料很难反射系统的红裂纹激光.
- 这种不够的反射率需要手动调整,增加设置错误和限制校准精度.
- 现有的系统需要手动翻译和旋转调整,这会影响表面监测的准确性和稳定性.
研究的目的:
- 开发一个改进的校准幻影材料和设计,以提高红裂激光的反射率和减少红裂激光的散射/衰减.
- 提出一种新的校准程序,尽量减少设置错误并改善坐标巧合.
- 与以前的设计相比,评估新幻影的检测准确性和稳定性.
主要方法:
- 一个新的校准幻影主要由PET100制造,因为它在不散射或减弱红裂激光的情况下具有优越的反射性而被选中.
- 新的幻影保持了与以前设计相似的形状,但采用了改进的材料性能.
- 在六个感兴趣区域 (ROI) 中评估了检测准确性和稳定性,并与机器和VOXELAN系统测量了坐标巧合.
主要成果:
- 与之前的Derlin幻影相比,新的PET100幻影显示出明显改善的检测准确性和稳定性.
- 新幻象的翻译坐标巧合大大减少 (例如,横向:0.28 ± 0.21毫米与1.07 ± 0.66毫米对比).
- 旋转误差仍然可比,但由于幻影的反射率提高和新的六度自由度沙发连接放置程序,整体系统稳定性得到了提高.
结论:
- 新的PET100校准幻影在检测精度和稳定性方面为VOXELAN系统提供了卓越的性能.
- 新幻象与其相关的放置程序的集成为精确的坐标校准提供了强大的解决方案.
- 这种优化的系统最大限度地减少了设置错误,从而导致更可靠的光学表面监控.
