Camera detects objects in low visibility conditions

This chip allows the devices to detect objects and create images through obstacles including fog, smoke, dust and snow.

The team is now working on a device for industrial applications that require imaging at up to 20 meters away. The technology could also be adapted for use in cars.

The researchers engineered the images using complementary metal oxide semiconductor (CMOS) technology.

Thereby, helping the driver or autonomous vehicle system navigate in dangerous conditions that reduce visibility. For example, on a car screen, the technology can show the contours and pixelated shape of objects, like another vehicle or a pedestrian.

"Technology that allows users to see in environments with impaired vision. For example, in an industrial setting, devices that use microchips can help inspect packaging.

From there, control production, monitor humidity, or see through steam. If the user is a firefighter, the technology can help see through smoke and fire," said Dr Kenneth K. O, Erik Jonsson School of Engineering and Computer Science.

The microchip emits beams of radiation in the terahertz (430 GHz) band of the electromagnetic spectrum from pixels no larger than a grain of sand. The beams pass through fog, dust and other obstacles that optical light cannot penetrate.

Then bounce off the objects and return to the microchip, which receives the signal to create the image. Without using an external lens, a terahertz camera includes a microchip and a reflector. As a result, it helps to increase the distance and image quality, as well as reduce power consumption.

The researchers engineered the images using complementary metal oxide semiconductor (CMOS) technology. This type of integrated circuit technology is used to manufacture the majority of consumer electronics. This research group was one of the first to demonstrate that CMOS technology is possible.

"The key thing about a terahertz camera is to produce small pixels and low power. You need to integrate the transmitter," said Dr. Wooyeol Choi, assistant professor of electrical and computer engineering at Oklahoma State University. receiver and antenna in such a small area".

Meanwhile, Dr Swaminathan Sankaran, Director of Design and Technical Staff at TI Kilby Labs, said: "The University of Texas and Oklahoma State University continue to explore technological innovations that will help shape the future. .

New research paves the way for improved raw angular resolution and system integration at a low cost and power."
