A design for Mosquito laser system
At the recent conference TED2010
a Mosquito laser system was demonstrated, designed to destroy mosquitoes – the carriers of malaria and other midges. The concept of the system and its functioning is very similar to the functioning of the missile defense complex "Patriot"
. First, the target detection occurs, then it's identification "friend or foe", tracking the target with laser illumination and in the end the target destruction with a high-power laser beam.
We think that having changed the design, it can be considerably simplified, made cheaper, and thus the system will become more widespread and available on the market.
Imagine a laser (with an enough-to-destroy-mosquito capacity) mounted at an angle (in a beam-down direction) on an elevated platform, which is rotating continuously and evenly. The laser beam will make a cone (with apex at the top), thus forming a virtual "photonic fence", - a barrier that no mosquito can go through.
To protect houses, picnic places, fields the platform is installed at a sufficient height, so that the objects, which need to be protected, were inside the cone "photonic fence".
For the effective operation of the system on a rotating platform 2 lasers can be installed: a combat laser and a targeting laser. They should be set so that their beams follow each other on the same trajectory tracing the same circle. The combat beam follows the targeting beam.
The targeting laser has little power and is used as a searchlight to illuminate the target. Any item will be lit up by the beam (the item will reflect the light). To a casual observer a mosquito that fell under the beam will look like a little bright flash (flame) on a dark background for a moment. This flash is detected by the management system of the combat laser. The management system will activate the laser for a short time to hit his target (the mosquito). Destructive beam will go along the same path as the targeting beam and therefore there is no need to use sophisticated target positioning and tracking system.
In order to protect people and animals at crossing the photonic fence one of the existing LPS (Local Position System) systems can be used. (For example, it can be based on RFID tags in a wrist strap). LPS monitors the movement of people and animals, and if they approach or cross the border photonic fence it blocks the lasers in this zone.
The advantages of this design:
- Mobility. The system can be easily moved from place to place and deployed in minutes. It will be appreciated and will be in demand among tourists, geologists, hunters, fishermen, picnic lovers. Conical dome protects from any blood-sucking flying reptiles .
- The system is simple in technical execution, all the necessary technology already exists.
- It is cheap, does not require the use of precision mechanisms. It's a plug & play design.
