• Abstract: This study explored the feasibility of using functional NearInfrared Spectroscopy to confirm suspects in simulated theft cases. Using functional NearInfrared Spectroscopy technology, a simulated theft case experiment was designed. Thirty volunteers were selected and divided into a criminal group, an informed group, and an innocent group. The experiment simulated a real interrogation scenario of a crime, using Guilty Knowledge Test’s method to develop questions. The brain activation levels and blood oxygen concentration changes of the suspects were measured when they lied and answered honestly. The study found that the spectral maps of the three groups of subjects all had unique characteristics. The criminal group showed significant activation in the prefrontal lobe and left temporal lobe regions, accompanied by an increase in blood oxygen concentration; The informed group showed partial activation of brain regions and an increase in blood oxygen content concentration; The brain regions of the innocent group were not activated, and the blood oxygen concentration tended to be stable without significant fluctuations. Based on this characteristic, near-infrared technology can accurately identify the suspect in a simulated theft case, demonstrating high accuracy and stability, providing strong support for the police in determining the suspect’s identity. 本研究探讨了近红外技术在模拟盗窃案件中的嫌疑确认的可行性，基于功能性近红外光谱技术，设计模拟盗窃案件实验，实验选取30名志愿者，分为犯罪组、知情组与无辜组，模拟犯罪真实讯问场景，使用犯罪情节测试法编制问题，测量犯罪嫌疑人说谎与诚实回答时的脑区激活程度以及血氧浓度变化。研究发现，三组被试的光谱图谱都具有其特征，犯罪组被试前额叶和左侧颞叶部分脑区显著激活，且血氧含量浓度也同时上升；知情组被试脑区激活程度部分激活并有血氧含量浓度上升情况；无辜组被试脑区无激活，血氧浓度趋于平稳，无明显波动。基于这一特性，近红外技术能准确识别出模拟盗窃案件的犯罪嫌疑人，展现出了极高的准确率和稳定性，为警方在确定嫌疑人身份方面提供了有力的支持。
