摘要： An optomechanical switching device, a control system, and a graphical user interface for a photopolarimetric lidar standoff detection that employs differential-absorption Mueller matrix spectroscopy. An output train of alternate continuous-wave CO2 laser beams [ . . . L1:L2 . . . ] is directed onto a suspect chemical-biological (CB) aerosol plume or the land mass it contaminates (S) vis-à-vis the OSD, with L1 [L2] tuned on [detuned off] a resonant molecular absorption moiety of CB analyte. Both incident beams and their backscattered radiances from S are polarization-modulated synchronously so as to produce gated temporal voltage waveforms (scattergrams) recorded on a focus at the receiver end of a sensor (lidar) system. All 16 elements of the Mueller matrix (Mij) of S are measured via digital or analog filtration of constituent frequency components in these running scattergram data streams (phase-sensitive detection). A collective set of normalized elements {ΔMi,j} (ratio to M11) susceptible to analyte, probed on-then-off its molecular absorption band, form a unique detection domain that is scrutinized; i.e., any mapping onto this domain by incoming lidar data—by means of a trained neural network pattern recognition system for instance—cues a standoff detection event.

摘要： An analog Mueller matrix data acquisition system (AMMS) acquiring middle-infrared Mueller (M) matrices of backscattering surfaces. The M-elements are measured by means of an active photopolarimetric sensor. The AMMS records nine M-elements simultaneously in groups of four modulo 2 incident continuous-wave CO2 laser beams—one incident beam is tuned to a fundamental molecular absorption cross-section by the aerosol of detection interest (analytic wavelength λa) while the other beam is detuned off that resonance band (reference wavelength λr) and in the closest vicinity to λa. Accordingly, those ΔM elements exhibiting susceptible behavior to the aerosol analyte, driven on-then-off its molecular vibrational resonance band, cues an identification event thus providing detection decision information. The AMMS is comprised of PEM reference frequency synthesizer, optical power regulation, data digitizer, and computer interface components in an interfaced and integrated framework that governs all operations of M-elements production by the photopolarimetric sensor.

摘要： Chemical agent warfare materials and their simulant liquids are identified on terrestrial surfaces at a distance by recognizing the contaminant's infrared fingerprint spectrum brought out in thermal luminescence (TL). Suspect surfaces are irradiated with microwave light that is absorbed into the surface and, subsequently, TL is released by the surface. An optics receiver collects the released TL radiant light, and a data acquisition system searches this TL radiant flux for the contaminant's fingerprint infrared spectrum. A decision on the presence or absence of any-of-N contaminants is done by a neural network system that acts as a filter through real-time pattern recognition of the contaminant's unique infrared absorption or emission spectra.

摘要： A Thermal Luminescent (TL) spectroscopy system and method for remote sensing and detection of surface chemical contamination involves irradiation of a target surface with energy from a near infrared pump beam, and measurement of TL liberated by that surface within a middle infrared (MIR) region. Fundamental molecular vibration modes of target contaminants present are briefly activated after the surface has been driven out of thermal equilibrium. An emissivity contrast between strata and target contaminant develops, peaks, and then subsides during a finite thermal window of detection opportunity in which detection of fingerprint identifiers for target contaminants is most probable. Target contaminant identification employs neural network models trained and tested against known molecular absorption frequencies of target contaminants. The use of a pump beam that radiates energy outside the MIR spectra of received TL reduces possible interference with the very weak MIR signals given off by target contaminants.
