University of Utah engineers have developed a camera that substitutes a regular pane of glass or any see-through window for the lens, in conjunction with a computer running an algorithm to interpret the images.

A team led by Utah's Rajesh Menon captured an image of the university's "U" logo and a video of an animated stick figure, both displayed on a light-emitting diode light board.

They directed a camera sensor linked to the side of a plexiglass window into the window, while the board was oriented in front of the pane at a 90-degree angle from the front of the sensor.

The resulting image from the sensor, assisted by a processor running the algorithm, is in low resolution but clearly identifiable. Menon says the method also can generate full-motion video and color images.

Cameras without lenses have many potential applications, such as security cameras, more compact augmented-reality glasses, and car windshields that capture information at multiple points.
