对激光全息照相法提取立体足迹的研究

The Construction of the Scope of Criminal Mediation

激光全息照相法提取立体足迹对实验环境和实验条件要求很高。分析了影响成像的诸因素,并对这些因素进行了探讨,总结了拍摄系统稳定性、调整光路、再现观察等提高全息照相成功率及全息图质量的具体做法。

Laser holography has a high requirement for experimental environment and conditions in obtaining stereo -footprints. The article analyzes and explores factors that influence the imaging, summarizes some specific methods of making holography successful and improving the quality of holograms,such as stabilizing the system of filming,adjusting light path as well as reappearance of observation.
