North Carolina State University (NCSU) researchers say they are developing new security imaging technology that would cost less than scanning devices used in airports to detect hidden weapons or contraband.
Inspired by a radio astronomy technique, the team is working to create an array of low-cost antennas and radio detectors that can detect and measure the radio waves in a targeted space.
The team says the imaging with reconfigured arrays in silicon (IRIS) camera would use as many as 20 radio or radar chips, each connected to multiple antennas. They note IRIS would make use of already developed, next-generation Wi-Fi radio chips operating at 60 GHz or automotive radar chips operating at 77 GHz, which would significantly lower the cost of the device.
The researchers say the information collected by the chips would be processed by algorithms developed by the team that turn the radio or radar data into an image. The team has used computer models to demonstrate the viability of the IRIS camera.
"Based on our simulations, an IRIS device will work as well as existing interferometers, but would be far less expensive and less bulky than existing millimeter-wave cameras," says NCSU doctoral student Vikas Chauhan.
