Abstract: A system comprises a processing system, a laser system, a telescope system, a detector system and optical systems operatively arranged such that the laser system may be capable of outputting multiple wavelengths to a common telescope system, and the detector system is capable of receiving signatures from the same telescope system, under the control of a control system. The processor system processes signals received from the detector system to determine substances identified by known signatures. For example, a plurality of detectors in the detector system each receive a range of wavelengths of the signatures received by the telescope system. For example, a variable beam diverger and variable beam expander operatively control expansion and divergence of the output the laser system. For example, a beam reducer and lenslet array may operatively transmit signatures via optical fiber bundle to one or more of the detectors.

Abstract: A method for flexible mounting piezoelectric devices at a spaced distance from a PC board by conductive adhesive so as to provide support to the device sufficient to withstand 50 g on three axes for 11 ms with minimal adverse effect on the operation and performance of the assembled structure. Also disclosed is a piezoelectric device flexibly mounted at a spaced distance from a PC board by conductive adhesive so as to provide support to the device sufficient to withstand 50 g on three axes for 11 ms with minimal adverse effect on the operation and performance of the device.
