Bioengineers create bionic 3D cameras that have bat sonar and bug eyes.
According to a press release from the university, UCLA bioengineers have created a new class of bionic 3D camera systems that can accurately mimic the multiview vision of flies and the natural sonar sensing of bats.
The camera can identify concealed things.
The new camera uses computational image processing to determine the size and shape of things that are concealed behind or around corners.
The new gadget makes use of a sonar technique similar to echolocation used by bats. High-frequency squeaks made by bats are picked up by human ears after bouncing off their surroundings. In order to establish where things are, what is in the way, and the proximity of possible prey, they compare differences in how long it takes for the echo to reach them and the strength of the sound.
