皮下出血类损伤的多波段光学检验

Multiband Optical Examination of Subcutaneous Hemorrhage Injury

探究多波段光源对皮下出血类损伤的显现效果,并对陈旧性皮下出血检验时限进行研究。利用多波段光源设备在365 nm、415 nm、450 nm、CSS、490 nm、510 nm、530 nm、555 nm、570 nm、590 nm及610 nm等不同波段光线对皮下出血部位进行照射并比对显现效果,对肉眼不可见的陈旧性皮下出血进行检验。在365 nm波段光源的照射下显现效果相对最为理想,检验对象中从皮下出血表现为肉眼不可见状态开始,最长2周内仍能检出皮下出血印迹。所提检验方法简便、快捷,为相应陈旧性皮下出血类损伤的司法鉴定提供了有效途径和科学依据。

In this study,we investigated the discernibility of subcutaneous hemorrhage injuries and the time limit of the examination for obsolete subcutaneous hemorrhage using a multiband light source.Different discernibility effects were compared through light irradiation at of 365-,415-,450-,CSS,490-,510-,530-,555-,570-,590-,and 610-nm wavelengths using a multiband light source.Moreover,an invisible,obsolete subcutaneous hemorrhage was examined.The effect was relatively ideal under the irradiation of the 365-nmwavelength light.A subcutaneous hemorrhage mark was detected up to 2 weeks in the invisible state.The proposed method is simple and fast,and it can provide an effective way and scientific basis for the forensic identification of obsolete subcutaneous hemorrhage injuries.
