Sure, it might look like a Viewmaster 3D from your childhood, but this here stripe projection 3D sensor from Fraunhofer IOF is so much less exciting. The concept is simple enough: the Kolibri projects a stripe pattern onto the subject, and then the two "eyes" capture slightly distinct angles of the image to compose a 3D model of the object based on the deducted geometry. The technology has been available for a while, but this is apparently the first device to cram it into such a small and portable form factor. Yeah... we'll stick with the Viewmaster.
