An important step in using a device like a 3D printer is having a 3D image of the device. Most people use computers and 3D-constructed models from computer modeling software to create the object. However, one new gadget may simplify the experience and put the tech in your pocket.

A team of CalTech researchers working with electrical engineer Ali Hajimiri have designed a new camera sensor that has the ability to translate a captured 2D image into a 3D image that's ready to print.

"The tiny chip, called a nanophotonic coherent imager, uses a form of LIDAR (Light Detection And Ranging) technology to capture height, width, and depth information from each pixel," The Verge reported. 

LIDAR isn't a new technology, as its particular theory of light tracking has been in use since the 1960s. However, Hajimiri told The Verge "by having an array of tiny LIDARs on our coherent imager, we can simultaneously image different parts of an object or a scene without the need for any mechanical movements within the imager."

The computer behind the sensor will have the ability to scan and check the wave state on a particular object and then determine the exact dimensions of the device. The researchers behind this chip say that its particular specs make it possible for it to track an object's physical dimensions down to the micron level.

While this all sound fantastic, the device is still fairly limited. The lab's current prototype only has a 16-pixel capacity, which is barely enough to capture the 3D dimensions of a coin-sized object without moving the device. However, as the chip's pixel range is increased and the equipment cost is lowered, it is likely that users will see the chip installed in smartphone devices in the future. Phone owners could also eventually see larger versions of the chip designed to capture the dimensions of a variety of objects.
