CalTech's new sensor, can turn your smartphone camera into 3D Scanner. CalTech with lead engineer Ali Hajmiri is working on such a scanner. It is a nano chip working on Light Detection and Ranging (LIDAR) technology. It will try and capture 3-D mapping by measuring the height, width, length and angle of each pixel. The light source used is Laser, and the resulting distortions are fed to the sensor discussed above. LIDAR is mostly used by defence systems and driverless cars. Hajmiri explains that using an array of LIDARs with a coherent imager; We capture 3-D images without having to resort to movement in between different angles to capture the entire object. Each pixel contains information about a part of the of the geometry, and we analyze it individually. According to researchers, accurate 3-D models to the precision of microns can be made with the help of this 3-D sensor.
Currently, the sensor has 16 pixels that aren't enough to create a 3-D model from one view, so it has to cover all of the parts in order to get a 3-D version. But further developments intend to include hundreds of thousands of pixels in order to get a model from a single view angle. This advancement will finally enable smartphones and similar gadgetry to have miniscule 3-D scanners that they can carry. Great future ahead of us, huh?
