激光诱导荧光法检验潜在痕迹

Using Laser to Induce Fluorescence to Test Latent Trace

本文报导了用氩激光束诱导潜在物证中残留的微量元素发荧光进行刑事技术检验的新方法。给出几个应用案例和实验结果,证明激光诱导荧光法检验潜在痕迹具有快速、可靠、不伤原件、不受痕迹遗留时间和承受客体限制的优点。

The anther report a new method of doing criminal technological test with Argon laser beam to induce fluorescence radiated by the left microelements which exist in the latent material evidence. It indicated a number of practical cases and their experimental results. It proved that using laser to induce fluorescence to test latent trace has the adventages of fastness, reliability, indicates no damage to original material evidences, or restriction on the left time of trace as well as the supporting objects. This method will surely become one of the important, indispensable, technological methods in criminal investigation work.
