Jim Wong, an engineer from Changzhou City, China, has developed a device called Photon Matrix, which can detect mosquitoes flying in the air and use laser beams to kill them.
Photon Matrix has a compact design, similar to a surveillance camera, but is integrated with a modern LiDAR sensor (Photo: IndieGogo).
This device has a compact design similar to a surveillance camera, integrated with a LiDAR sensor (Light Detection and Ranging - Technology to detect and locate using light).
LiDAR is a technology that uses sensors to measure distance with a continuously emitted laser beam, then collects reflected pulses from surrounding objects back to this sensor, similar to the way radar works.
The LiDAR sensor emits a laser beam to continuously scan to detect mosquitoes in space, then a high-power laser beam will be fired to kill the mosquitoes (Photo: IndieGogo).
Photon Matrix will emit a laser beam to detect mosquitoes flying in the air. If a mosquito is detected, the target will be “locked” and a second high-power laser beam will be released immediately to kill the mosquito. The time from when the mosquito is detected until the laser beam is released to kill it lasts only 0.03 seconds.
This device can detect insects flying in space at a maximum speed of 1m/s. Meanwhile, mosquitoes have an average flying speed of 0.4 to 0.6m/s, so they can be easily detected and destroyed by the Photon Matrix.
In addition to mosquitoes, the device can also kill some small harmful insects, but with house flies, an animal that can fly at speeds of up to 6m/s, the effectiveness of the Photon Matrix will be significantly reduced.

Photon Matrix is developed with 2 versions, including the Basic Edition (basic option) which will have a 90-degree scanning range and kill mosquitoes at a distance of 3m. If upgraded to the Pro version, the device will be able to kill mosquitoes at a distance of 6m.
Jim Wong says both versions are capable of detecting and killing up to 30 mosquitoes per second. Notably, the Photon Matrix's laser system allows the device to operate in complete darkness.
Photon Matrix also has built-in sensors to detect large objects such as people or pets. If any object enters the LiDAR system's scanning range but is large, the mosquito-killing laser will not be activated.
The device can be used with a fixed power source or with a rechargeable battery, making it easy to move around. Each full charge of the battery can be used continuously for 8 or 16 hours, depending on the version.
Photon Matrix supports waterproof feature, can be installed and used outdoors. However, Jim Wong advises users not to install the product without cover because rainwater can reduce the effectiveness of the scanning sensor.

Photon Matrix is currently a crowdfunding project and has raised more than Jim Wong's target, allowing the engineer to begin developing a commercial product.
The Photon Matrix is expected to be available in March next year, priced at $697 for the Basic version and $897 for the Pro version. Those who have contributed funds to support the project from the beginning will be able to buy the device at a preferential price of $468 for the Basic version and $629 for the Pro version.
The developer of Photon Matrix claims to have integrated safety standards into the device to prevent the product from accidentally “firing” on people or pets in the house.
Despite safety claims, there is no evidence of international testing, and the device has sparked controversy in the community. Many have expressed concerns about the impact on beneficial insects such as bees or fireflies if the system cannot accurately distinguish.
