Multiband Optical Examination of Subcutaneous Hemorrhage Injury
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-nm-wavelength 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.
