Methods, systems and computer program products for identifying components of an unknown mixture using spectral analysis techniques. The method includes comparing the spectrum of the unknown mixture with the spectra of library compounds to obtain candidate mixture combinations. A model is generated for each of the candidate mixture combinations based on a modeling metric. A residual spectrum is computed corresponding to each of the candidate mixture combinations by removing the spectrum of each of the compounds of the candidate mixture combination from the spectrum of the unknown mixture. One or more potential compounds are identified by comparing the residual spectrum with the spectrum of library compounds. The potential compounds are added to the candidate mixture combinations to generate an updated list of the candidate mixture combinations. The search algorithm repeats the steps described above on the updated candidate mixture combinations, until a first termination condition is satisfied.

This invention involves an apparatus to measure the nuclear quadrupole (NQR) response of a specimen using three frequencies. Three-frequency NQR involves excitation of at least two transitions that causes an observed signal at a third transition frequency. Thus, the transition excited and detected is not irradiated at all. This reduces undesirable interfering signals due to the excitation, for example as a result of acoustic ringing and/or tank circuit ring-down, since the excitation is not applied at the frequency that is detected. This invention will be particularly useful to detect substances selected from the group consisting of explosives and narcotics using nitrogen NQR.

Described herein is a system for reducing vibration of a lens. One way to reduce vibration is through a programmable processor configured to divide a lens movement requirement into smaller lens movements and then insert a wait time after completing the smaller lens movements. The smaller lens movements can be repeated for subsequent smaller lens movements until all the remaining smaller lens movements have been completed. The system may include an actuator configured to move the lens; and wherein the lens movements are completed within a processing time of one image frame.

In a method for reducing lens vibration in an image capture device, a lens movement requirement is broken up into N smaller lens move steps, and the lens is moved a first of the N smaller steps. A wait time is inserted after completing the first of the N smaller steps, and then the moving and inserting steps are repeated until the remaining N smaller move steps have been completed. The image capture device includes a voice coil motor for moving the lens under control of a controller in accordance with the lens movement requirement, which reflects a determined lens position. The voice coil motor includes springs which impart vibration to the lens during lens movement. The vibration imparted by the springs to the lens is thus actively dampened during the lens movement to the determined lens position.
