According to foreign media reports, researchers at Purdue University and Stanford University have developed a laser light sensing technology. The new technology is said to be more powerful, more reliable, and less expensive than current sensing technologies. In the future, this technology may be applied to autonomous vehicles. Let's take a look at the related content with the car electronics editor.

It is reported that the two universities are testing and using laser beam steering, which is based on the interaction of light and matter between silicon-based metasurfaces and short light pulses. The short light pulse is generated by a mode-locked laser with a frequency-comb spectrum.
Such beam steering devices can scan a large angle of view, which takes only a few nanoseconds or picoseconds. In contrast, the current technology takes several microseconds.
Laser beam control devices can be used in navigation, space flights, radar applications, imaging, label scanners, robotics, archaeology, mapping, and atmospheric physics. The increase in laser scanning speed is directly related to the improvement of frame rates and imaging resoluTIon.
The researchers claim that this is a chip-compaTIble technology that does not require any other energy source. In addition, another key element of this innovative technology is the application of a superficial surface with patterned silicon film.
Researchers claim that another major element of technological advancement is the use of photonics. This super-faceted surface provides a simple, compact and energy-saving product solution for photonic design. Combining these two technologies provides a simpler solution.
With the new system of the research team, the transmission frequencies of the various structural components are slightly different, which means that there is no need to continuously adjust the position of each antenna during the entire process, and there is no energy consumption.
At present, the challenge for researchers is how to expand the scale of the realization of this innovative technology. The R&D team is looking for investors, partners and license agreements that may be required for this technology development.
In the early days of technology development, the technology was applied to scanning equipment in stores, airports or other fields. In the future, the technology will shift to autonomous vehicles and will work with automotive OEMs.
