Most approaches to capturing 3D models of real-world objects involve multiple cameras (http://www.engadget.com/2012/01/22/orcam-sphere-constructs-detailed-digital-3d-models-of-wares-whi/?utm_source=Feed_Classic&utm_medium=feed&utm_campaign=Engadget) that are rarely cheap, and are sometimes tricky to calibrate. The University of Glasgow (http://www.engadget.com/2012/04/18/university-of-glasgow-scientists-print-drugs-in-3d-pave-the-way/?utm_source=Feed_Classic&utm_medium=feed&utm_campaign=Engadget) has developed a method that ditches those cameras altogether. Its system has four single-pixel sensors stitching together a 3D image based on the reflected intensity of light patterns cast by a projector. Reducing the pixel count lowers the cost per sensor to just a few dollars, and extends the sensitivity as far as terahertz (http://www.engadget.com/2012/08/25/harvard-makes-distortion-free-lenses-from-gold-and-silicon/?utm_source=Feed_Classic&utm_medium=feed&utm_campaign=Engadget) wavelengths. Real-world products are still a long way off, but the university sees its invention as useful for cancer detection and other noble pursuits. Us? We'd probably just waste it on creating uncanny facsimiles (http://www.engadget.com/2013/05/07/3d-systems-star-trek/?utm_source=Feed_Classic&utm_medium=feed&utm_campaign=Engadget) of ourselves.
