📸 The new tiny camera, the size of a grain of salt, can take pictures inside the body

Scientists have developed a tiny camera with an area about the size of a grain of salt, that can produce sharp, full-color images. The groundbreaking technology has the potential to revolutionize in-body and brain imaging, robotics and self-driving vehicles.

Traditional cameras rely on an array of lenses to focus light and create sharp images. To make the cameras miniaturized, the researchers use meta-optics, which use nanostructures that capture and re-emit light. These tiny antenna-like structures have been used in tiny cameras before, but the image quality has been unsatisfactory.

To get around these limitations, researchers at Princeton University and the University of Washington used machine learning. They created an AI model to test different configurations of the tiny antennas on the surface of the microcamera. By combining the physical properties of the tiny camera with computational optimization, the team has achieved much better images than before.

Transformational applications

This innovative little camera can have a number of different uses. One possibility is to replace the multiple cameras on the back of smartphones with a single ultra-high-resolution camera. In addition, microcameras can improve endoscopic surgical approaches and open up new possibilities for brain imaging.

According to Felix Hyde, Professor of Computer Science at Princeton University and lead author of the study, developing this tiny camera allows us to think in entirely new ways when building different types of devices in the future. As technology evolves, it can pave the way for new imaging possibilities that were previously unimaginable.
