Camera-less Smart Laser Projector

We introduce here our latest ‘smart laser projector’ prototype, i.e, a modified laser-based projector capable of augmenting all kind of surfaces while simultaneously using the laser as a scanning beam used for gathering information about that surface shape, texture, reflectivity, relative motion, etc. ‘Augmenting’ surfaces (including tables, desktops, walls and floors, but also human skin, paintings, market products on a shelf, etc) means here alphanumeric or iconic annotation, highlighting features invisible to the naked eye (for instance veins under the skin, small scratches or oily spots on surfaces), cueing (using flashes of light for marking secure perimeters or indicating dangerous obstacles) and line and contour enhancement for practical or aesthetic purposes. This device fits in many ways the definition of a ‘smart projector’ as described in [1] but presents a number of advantages with respect to the classical projector/camera configuration.
