Research of Object Microimpurtity Measurement Based on Stroboflash Method

摘要：

we discuss the Stroboflash method that is used to detect microimpurtity elements in some objects or on the objects surface. Stroboflash method is a non-contact detecting technique and a more sensitive expertise through analyzing objects luminous radiation characteristic when the objects are excited by external source such as visible light, X-ray, γ-ray and electron beam etc. By analyzing the parameters of luminous radiation time resolution and luminous radiation time decay-rate, we can obtain the microimpurtity characteristics plot. The experimental results indicate that the measurement has more accuracy and sensitivity. The object microimpurtity measurement method can be used in criminalistics, medicolegal expertise, customs office and taxation department etc.
