International Classification:

G01N 2572

US Classification:

374 45, 374124, 374 5

Abstract:

Chemical agent warfare materials and their simulant liquids are identified on terrestrial surfaces at a distance by recognizing the contaminants 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 contaminants 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 contaminants unique infrared absorption or emission spectra.

Abstract:

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 COlaser beams [. . . L:L. . . ] is directed onto a suspect chemical-biological (CB) aerosol plume or the land mass it contaminates (S) vis-à-vis the OSD, with L [L] 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 (M) 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 {} (ratio to M) susceptible to analyte, probed on-then-off its molecular absorption band, form a unique detection domain that is scrutinized; i. e.

International Classification:

G01J 3/447

US Classification:

356322, 356246, 356338

Abstract:

A system, apparatus, and method of generating Stokes vectors, a Mueller matrix, and polarized scattering from an aerosol aggregate includes providing an incident infrared laser beam; causing the incident infrared laser beam to be polarization-modulated using variable stress/strain birefringence imposed on a ZnSe crystal; defining a Stokes vector associated with the incident infrared laser beam; scattering the incident infrared laser beam from an aggregate aerosol comprising interferents and analyte particles; producing a scattered-beam reactant Stokes vector by causing the scattered incident infrared laser beam to be polarization-modulated; generating a Mueller matrix by taking a transformation of the Stokes vector; and identifying the analyte using the Mueller matrix. The Mueller matrix may comprise M-elements that are functions of a wavelength of the infrared laser beam, backsattering orientation of the infrared laser beam, and a shape and size of the interferents and analyte particles.

International Classification:

G01N 21/35
G01N 21/63

US Classification:

2503416, 25033908

Abstract:

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.
