This system is seen in the water and on land. A revolutionary achievement by scientists

Due to the fact that machines can see, more and more popular technologies have appeared, for example in the form of autonomous cars. Unlike biological systems, synthetic vision systems cannot self-evolve.

Scientists from CSAIL Lab, Gwangju Institute of Science and Technology, and Seoul National University decided to make their progress a little easier by creating a ground-breaking, revolutionary vision system for monitoring the environment both underwater and on land. The prosthetic eye absorbs its inputs with a mixture of materials that process and “understand” light.

The team members combined a set of micro-flat lenses with an array of photodiodes in patterns superimposed on a three-dimensional spherical structure. As a result, light rays from multiple sources always converge to the same place on the image sensor. This happened regardless of the refractive index of the environment.

The solution was tested in air and water experiments. The task of the device was to photograph five objects from different distances and directions. The system has been shown to deliver consistent image quality and a field of view of approximately 360 degrees in both environments. In the case of previous systems of this type, they dealt only with one of the two variables.

Our system can be useful in developing unconventional applications such as panoramic motion detection and obstacle avoidance in a constantly changing environment, as well as augmented and virtual reality. Currently, the size of the semiconductor optics module commonly used in smartphones, automobiles, and surveillance/surveillance cameras is limited to the laboratory level. Young Min Sung, GIST

Interestingly, in 2013, a camera design with a wide field of view that simulates the compound eyes of an insect appeared. In turn, two years ago, a camera with a wide field of view, imitating a fish’s eye, was presented. However, they had trouble reaching the 180 degree field. On the other hand, the advanced 360-degree systems turned out to be quite huge.
