The World’s Smallest Video Camera Is the Size of a Grain of Sand

Developed with technology created by researchers at the University of Washington and manufactured by OmniVision Technologies, the OmniVision OV6948 has been recognized by the Guinness Book of World Records as the smallest commercially available image sensor in the world. What is the size of the camera? Only 0.65 x 0.65 x 1.158 mm, roughly the size of a grain of sand! Great, now I will never be able to find my camera again on vacation.

This nano camera is built on a metasurface made up of 1.6 million cylindrical poles that function as a camera sensor. Each of these posts acts as an optical antenna that receives light and shapes the optical wavefront.

The tiny camera is capable of capturing 200 x 200 resolution (40,000 pixels) images at 30 frames per second. For reference, a Gameboy screen is 160 x 144, so it’s better than that AND in color. Of course, it’s not HD, but the camera was designed to fit inside HUMAN VEINS to help doctors during diagnosis and surgery. What it lacks in high definition, it more than makes up for by being able to fit absolutely anywhere.

The optical sensor is made up of 1.6 million cylindrical posts that each receive light and require a custom algorithm to process the images, which in their raw form are blurry (see above before and after processing). Technology! Then stop a subatomic camera.
