摘要: Systems and methods for fast sensitive standoff surface-hazard detection with high data throughput, spatial resolution degree of pointing flexibility. The system comprises a first hand-held unit that directs an excitation beam onto surface is located distance away from the optical subsystem captures scattered radiation as result light. connected via link includes bundle fibers, to second unit, called processing unit. fiber-coupled spectrograph convert spectral data, processor analyzes collected detect and/or identify hazardous substance. may be contained within body-wearable housing or apparatus so together form man-portable assembly. In one embodiment, can continuously without interruptions scan 1-meter while generating Raman spectral-frames at rates 25 Hz.
