Abstract

Described herein is a method and system for providing a countermeasure against laser detection systems using nanocomponent material that is tailored to cloak or obscure a target from detection by transmitted laser radiation. The nanodot material absorbs and/or down-converts the transmitted laser radiation. Similarly, described herein is a method and system for providing a countermeasure against laser systems intended to blind a target through the use of a specifically engineered nanocomponent material for absorbing and/or down-converting the radiation from the laser system.

Claims (25)

1. A method for obscuring a target from laser effects comprising:

engineering a first nanocomponent material to absorb at a first transmitted radiation wavelength of a first laser transmission device; and

releasing the first nanocomponent material in the vicinity of the target, wherein the first transmitted wavelength of the first laser transmission device is absorbed by the first nanocomponent material, prior to reaching the target;

wherein each of the multiple first nanocomponents is encapsulated in, or attached to, a first polymer matrix; and

wherein the first polymer matrix is selected from the group consisting of polystyrene and polymethylmethacrylate (PMMA).

2. The method according to claim 1 , further comprising, adding the first nanocomponent material to a known obscurant prior to releasing the first nanocomponent and the known obscurant in the vicinity of the target.

3. The method according to claim 1 , wherein the known obscurant is smoke.

4. The method according to claim 1 , wherein the first nanocomponent material is comprised of multiple first nanocomponents, wherein each first nanocomponent is less than 100 μm in diameter.

5. The method according to claim 1 , wherein the first nanocomponent material is a semiconductor material.

6. The method according to claim 5 , wherein the semiconductor material is selected from Group II-VI and Group III-V materials.

7. The method according to claim 1 , wherein the first nanocomponent material is comprised of multiple nanocomponents, wherein each nanocomponent is selected from the group consisting of nanodots, nanorods, nanowires, and nanotubes.

8. The method according to claim 1 , wherein the target is a human or a group of humans.

9. The method according to claim 1 , wherein the target is non-human.

10. A method for obscuring a target from laser effects comprising:

releasing a first nanocomponent material in the vicinity of the target, wherein a first transmitted radiation of a first laser transmission device is absorbed by the first nanocomponent material, prior to reaching the target;

wherein the first nanocomponent material is comprised of multiple first nanocomponents, wherein each first nanocomponent is less than 100 μm in diameter;

wherein each of the multiple first nanocomponents is encapsulated in, or attached to, a first polymer matrix; and

wherein the first polymer matrix is selected from the group consisting of polystyrene and polymethylmethacrylate (PMMA).

11. The method according to claim 10 , further comprising, adding the first nanocomponent material to a known obscurant prior to releasing the first nanocomponent and the known obscurant in the vicinity of the target.

12. The method according to claim 10 , wherein the known obscurant is smoke.

13. The method according to claim 10 , wherein the first nanocomponent material is a semiconductor material.

14. The method according to claim 13 , wherein the semiconductor material is selected from Group II-VI and Group III-V materials.

15. The method according to claim 10 , wherein the first nanocomponent material is comprised of multiple nanocomponents, wherein each nanocomponent is selected from the group consisting of nanodots, nanorods, nanowires, and nanotubes.

16. The method according to claim 10 , wherein the target is a human or a group of humans.

17. The method according to claim 10 , wherein the first nanocomponent material is comprised of multiple first nanocomponents, wherein each first nanocomponent is less than 100 nm in diameter.
