Portable device for detecting explosives, including a device for generating and measuring light emission of an indicator

摘要

A portable appliance (100) for detecting explosives has a device (200) for generating and measuring the light emission of an indicator (120). The indicator has a carrier (122) and a plurality of indicator substances (125-1, 125-2) that can be incident by the analyte (190), the indicator substance being a thin layer of the carrier (122 ) And can be positioned in the indicator area (130) using the holding device (180). The indicator material is placed in different regions of the carrier (122) so that the indicator material in the indicator area (130) represents a pattern of indicator material depending on location. The apparatus (200) has a plurality of excitation radiation sources (210-1, 210-2) that emit quasi-monochromatic excitation radiation such that the radiation area represents a pattern of radiation sources depending on location. Located at various locations within the radiation area (240). [Selection] Figure 1
