    Abstract: The present invention provides an apparatus and method for identification of a chemical or a biological agent using a handheld or portable unit in non-laboratory conditions. More specifically, the system uses a portable unit containing an array of tunable lasers, which are stabilized with a digital controller. The apparatus excites the sample under test with a narrow band light source used to excite fluorescence. The fluorescent response is detected with a broadband detector and digitized. The information is then sent through wireless means to a remote server where a database of appropriate signatures is used to determine the identity of the sample. The results are sent back to the portable unit or to a Personal Digital Assistant (PDA).

    Abstract: A multichannel fluorosensor includes an optical module and an electronic module combined in a watertight housing with an underwater connector. The fluorosensor has an integral calibrator for periodical sensitivity validation of the fluorosensor. The optical module has one or several excitation channels and one or several emission channels that use a mutual focusing system. To increase efficiency, the excitation and emission channels each have a micro-collimator made with one or more ball lenses. Each excitation channel has a light emitting diode and an optical filter. Each emission channel has a photodiode with a preamplifier and an optical filter. The electronic module connects directly to the optical module and includes a lock-in amplifier, a power supply and a controller with an A/D converter and a connector. The calibrator provides a response proportional to the excitation intensity, and matches with spectral parameter of fluorescence for the analyzed fluorescent substance.
