Abstract

This invention relates to a method and system for remote detection of a targeted substance by the appropriate application of a probing signal that induces molecular resonance in the target substance to create an identifiable signature or response. In the preferred embodiment, signals transmitted are an Infrared laser beam, amplitude modulated in the range of 100 kHz frequency. The probing signal stimulates molecular resonance of the target substance which produces characteristic electron signal responses that are detected by IR detectors. A software program is used to process the electrical response signals and to compare them with electrical response signals stored in a database of known substances, thus allowing the target substance to be identified. The system may also be used to locate targeted substances. Also disclosed is an artificial ground device that provides a positive ground that provides consistent responses.

Claims

1. An ion acoustic remote substance identification and location system, comprising:

a. an ion acoustic voltage radiation source;

b. means for ionizing an intermediate chemical to produce a probing signal of a desired frequency and amplitude capable of propagating a voltage from said ion acoustic voltage radiation source to a desired target substance to produce non-destructive molecular resonance therein;

c. means to transmit said voltage and said probing signal to a target substance to cause said target substance to undergo molecular resonance and produce a characteristic electrical response signal;

d. means for detecting with directional shielding said electrical response signal produced by said target substance; and

,

e. means to identify said target substance based on said electrical response signal detected by said means for detecting.

2. The system, as recited in claim 1, wherein said means for detecting with directional shielding said electrical response signal is performed by a transmitting a probing signal to a target substance that produces a target signal picked up by an electrode surrounded by a metallic outer shield and an insulative inner shield, said electrode being connected to a transformer assembly that includes a metallic outer housing.

3. The system, as recited in claim 2, wherein said outer housing of said IR detector and said transformer assembly are connected to an artificial grounding device.

4. The system, as recited in claim 3, wherein said artificial grounding device includes an outer housing with a ground port connected that connects to the grounds on said IR detector and said transformer assembly, said artificial grounding device includes a IR diode, that produces a IR signal inside said outer housing with a current is applied to said grounding port, said artificial grounding device also including an opaque, insulative shield that is slightly small than said outer housing thereby creating a window through which said IR signal from said IR diode may be transmit to ionize the air located outside said outer housing.
