In a breakthrough, a team of scientists including an Indian-origin has developed world’s first flexible sheet camera which is flexible enough such that it can be wrapped around any object to capture the image, a feat which conventional camera cannot achieve. The next-gen camera sheet has the capability to revolutionize the way we click pictures and carry cameras.
Just like liquid adapts the shape of a container similarly, the sheet camera boasts an array of flexible lens which can adapt its optical properties according to the shape of the container. This induced flexibility of the camera sheet and its optical adaptation enables it to capture high-quality images over a wide range of sheet deformations.
“While the camera industry has made remarkable progress in shrinking the camera to a tiny device with ever increasing imaging quality, we are exploring a radically different approach to imaging,” said lead study author Shree K Nayar from Columbia University.
Such a revolutionary system could be attached to anything including cards, clothes, it could be wrapped around all kinds of things, poles, cars and furniture to capture wide range of photos.
While explaining about the working of the “flex-cam”, Nayar said that the camera contains basically two parts — a flexible detector array and a thin optical system to project a high-quality image on the array.
Conventional cameras have rigid lens with fixed focus length and bending it could lead to distorted image filled with gaps and missing information. However, researchers solved the problem using a lens with variable focus length that could be bent in any direction to capture high-quality images.
