Miniature 3D sensor maps surgical field; scope small enough for use in neurosurgery

http://www.visionsense.com/hp.html

Visionsense’s miniature 3D sensor optically maps the surgical field, based on (and imitating) the eye of a bee. A single sensor is divided into hundreds of thousands of tiny “eyes” looking in different directions, using an array of micron-sized elements.  The elemental information is translated into left and right eye images, resulting in a clear stereoscopic view,  bypassing the diffraction limit that restricts current miniature cameras.

In neurosurgery, scopes must be very small in diameter to pass through narrow ports, such as the nose.  Most 3D scopes rely on two optical channels, each containing a single sensor. Each sensor collects two separate images that are combined to give the appearance of three dimensions as a user looks at the screen – mirroring the sight of the human eye.   Using their single sensor system, Visionsense has developed a high quality image producing scope that is small enough to operate on the brain.
