US12546578 - Countermeasure device

A laser weapon countermeasure device is described. The laser weapon countermeasure device comprises a sealed capsule having a filler disposed therein. The filler comprises either: a reflective particulate metal; or a precursor for a reflective metal or reflective metal alloy. The capsule is configured to burst in air such that the filler disperses into an aerosol. A countermeasure launcher and a vehicle comprising a countermeasure launcher are also described.

The patent describes a laser weapon countermeasure device that utilizes a sealed capsule containing a filler made from reflective metal precursors, which disperses into an aerosol when the capsule bursts in air. The capsule is designed to release its contents when exposed to air or a laser beam, enhancing its effectiveness as a countermeasure against laser weapons.

Claim 1

1 . A laser weapon countermeasure device, comprising: a sealed capsule comprising a capsule wall having a filler disposed therein, the capsule wall being formed of a material or coated with a material which is configured to release the filler when exposed to air or laser beam, the material or coating heats when exposed to air or laser beam which heats the filler thereby releasing the filler or a material which disintegrates when the capsule is travelling at a speed greater than a threshold to release the filler, the filler comprising a precursor for a reflective metal or a precursor for a reflective metal alloy, the precursor comprises one of triethyl aluminium, a pyrophoric organometallic molecule, or a metal hydride, each of which form a reflective metal or reflective metal alloy when exposed to light. a sealed capsule comprising a capsule wall having a filler disposed therein, the capsule wall being formed of a material or coated with a material which is configured to release the filler when exposed to air or laser beam, the material or coating heats when exposed to air or laser beam which heats the filler thereby releasing the filler or a material which disintegrates when the capsule is travelling at a speed greater than a threshold to release the filler, the filler comprising a precursor for a reflective metal or a precursor for a reflective metal alloy, the precursor comprises one of triethyl aluminium, a pyrophoric organometallic molecule, or a metal hydride, each of which form a reflective metal or reflective metal alloy when exposed to light.
