Making 3D images is typically a bit of a production. One method is to use two lenses to create a stereoscopic image. Harvard researchers have come up with a way to create 3D images using a single lens without requiring new hardware.
The method works by taking two images with a camera or microscope. The camera doesn't move, but each image is focused at a different depth. Those images are then run through a computer that calculates the angle of light to each pixel. This allows the computer to determine what the image would look like if taken from a different position, the way the second lens on a 3D camera would see it.… Read more
