Abstract:
1. A detection system, comprising: a hand-held unit comprising a light source configured to optically interrogate a surface and collection optics configured to capture scattered optical energy from the surface; a manportable unit connected to said hand-held unit and configured to receive said scattered optical energy captured by the hand-held unit, comprising a spectrograph that is configured to convert said scattered optical energy to spectrum data and a computing device that is configured to analyze the spectrum data produced by the spectrograph in the manportable unit; and an air collector unit that is configured to collect air and to separate particles in the collected air for deposit onto a collection surface, wherein the air collecting unit comprises a port configured to permit optical access to said collection surface by said hand-held unit and a support structure configured to removably support said hand-held unit in a position for optical interrogation of said collection surface; wherein the hand-held unit is configured to be removable from said air collector unit to permit the manportable unit and the hand-held unit to be carried away from the air collector unit for use as an integrated portable detection system by a user.
