An insect-killing laser system causes damage at a glance

Photonic Fence can automatically detect harmful insects and shoot laser to burn animals for 25 milliseconds.

Seattle-based Intellectual Ventures Lab develops Photonic Fence devices that can detect and kill pests, Engadget reported on June 26.

Photonic Fence creates an infrared light wall with a capacity of about 30W, which can distinguish many harmful insects, even between male and female mosquitoes, through their flight.

Within 25 milliseconds, you have the body of the insect on the ground.

The camera and optical system make it possible to detect suspicious animals within a range of 100 meters to determine the shape, speed, acceleration and frequency of the wings.

If the animal's parameters match the programmed insect list, the device automatically shoots out a laser beam. "Within 25 milliseconds, you have the body of an insect on the ground," said Arty Makago, chief technical officer of the project. Makago says the device can kill 20 insects per second in 30 meters wide, 3 meters high.

The US Department of Agriculture has installed equipment at a site for testing. If tested successfully, American farmers may soon buy the product on the market to replace pesticides.
