摘　　要：深色衣物上的潜在血痕在可见光的照射下很难显现出血痕的印记,文章中从红外线照相这一物理技术研究入手,以深色衣物上潜在血痕为主要研究对象,以不同客体血痕印记的不同显现方法进行实验探究,来论证以红外照相显现潜在血痕的可能性。在此基础上,进一步研究不同衣服材料上血潜手印的显现,能够在刑事案件侦查过程中提供有力帮助。Dark clothing on potential bloodstain under visible light irradiation shows a bloodstain imprint diffi- cultly, starting with the infrared photography which is a physical technology research, take the potential blood- stains on dark clothing as the main study objec ,the experimental study will be done by different manifestation methods with different object bloodstains mark and it demonstrates the possibility of showing potential blood- stains by infrared camera. On this basis, the showing of latent blood fingerprints on different clothes is further researched, which can provide the powerful help in the criminal investigation process.
