Dry stains of blood, semen and saliva invisible to the naked eye could be detected by their inherent short wavelength UV luminescence. The source was a frequency quadrupled Nd:YAG laser, emitting at 266 nm. A plausible explanation for this phenomenon as due to the presence of amino acids in these secretions is presented.
肉眼不可见的干涸血迹、精液斑迹和唾液斑迹可通过其固有的短波长紫外线发光来检测。光源是一台四倍频钕钇铝石榴石激光器，发射波长为266纳米。文中提出了一种似是而非的解释，认为这种现象是由于这些分泌物中存在氨基酸所致。
