Every Single Gadget Could “See” With World’s Tiniest, Simplest Camera | Fast Company
Picture a camera that has no lens, no moving parts, costs fractions of a penny to make, and sees as dimly as a short-sighted worm. Doesn’t exactly sound like a game changer—but it is.
Cornell scientists have achieved the breakthrough by producing what’s called a Planar Fourier Capture Array camera from a super-cheap material, doped silicon, that’s currently used in all sorts of chip technology. It’s just one-hundredth of a millimeter deep and a half a millimeter on each side, which means several of them could fit on the head of a pin. The magical aspect of the cam is that it doesn’t need a lens because it makes use of the wave-like properties of light to work out what it’s looking at, and all the image construction is done by algorithms in a computer later.
