Israel Develops Low-cost Infrared Sensor For Lidar

- Apr 03, 2018 -

  Researchers at Ben-Gurion University of the Negevet, a prestigious research institute, say they have developed a low-cost infrared sensor that can make the world's thinnest night vision glasses.And innovates the infrared night vision application of the smart phone and the self-driving car.


  Professor Gabby Sarusi of the Ilse Katz Institute of Nano-Science and Technology at the University of Ben-Gurion has developed a stamp shaped device that reads infrared light at 1500nm wavelengths, according to a report by Moms Consulting.The infrared light is converted on the other side to visible light visible to the human eye.The device is based on a thin film that is only 0.6um thick, including nanomaterials, columns and ultrathin metal foil, a magical film that converts infrared light into visible light.


  "the film can be assembled in front of ordinary glasses or binoculars to transform them into infrared devices.Films can also be made on conventional visible light sensors, making them infrared sensors that 'see' infrared light that the human eye cannot see, "Sarusi said."

  According to Sarusi, the technology could replace bulky night-vision devices with lightweight, low-power glasses for battlefield soldiers.The technology is largely based on nanotechnology and physics, and the only electronic component included is a tiny battery.


  But the technology has a wide range of promising applications, such as self-driving cars.Devices using this technology can turn infrared light into visible light, enhancing vision for self-driving cars at night, in poor sight conditions such as rain, snow, fog, and so on.


  "an infrared sensor often costs about $3000, while a conventional vision sensor for a self-driving car costs about $1 or 2," Sarusi said. "so, plus the nanofilm technology we've developed, the overall cost is just around $78.This will significantly reduce the application costs of autonomous cars. "


  "all kinds of sensors are the foundation of self-driving cars, and they need to become more economical."the film technology can be used for camera sensors that help autonomous cars' see 'farther and more clearly, as well as LiDAR (lidar) sensors that are aware of the vehicle's environment."


  Another promising application of the technology, according to Sarusi, will be smartphones, which will lead to more innovative infrared vision applications.


  Ben-Gurion University has started licensing the technology and set up startups to further develop products for commercialization.According to Sarusi, it could take two to three years for the technology to be truly commercialized.
