Improvised
explosive devices employing laser initiation have been used on several occasions
in the 1990s. Securesearch,
Inc.
now offers several types of inert training aids operating on the coherent light
activation principle. Laser light is a concentrated beam which can be projected
very accurately at a target. In an I.E.D. application a photocell and attached
processing circuitry are placed in a target area where the victim is expected to
pass by, usually in a vehicle convoy. The circuitry is attached to a detonator
and explodes. The photocell unit is insensitive to ordinary light, but laser light triggers a change in resistance which is sensed by the detecting circuitry. The photocell unit and laser light transmitter are positioned on opposite sides of an anticipated approach route, mounted on tripods. The
bomb can be detonated in one two ways: 1.
When the target vehicle cuts the laser beam which is continually projected from
the laser to the photocell unit. This activates a relay or silicon-controlled
rectifier sending a power pulse to the detonator. 2.
When the bomber activates the laser unit to project a beam to the photocell
(command detonation), the beam triggers the detector circuit. The circuit sends
a power pulse to the detonator. Our
inert training aid comes with a tripod-mounted, battery-operated laser unit
rated at 1.2 milliwatts. The other half of the package is a photocell and
detector/trigger circuit, attached to an inert detonator containing a
light-emitting diode and piezo whistle. The LED and whistle offer visual and
audible proof of "detonation". An optional low-power telescopic sight
is available for precision aiming over longer distances. The
system can be supplied in several formats. |
