ILLINOIS: A research team at Northwestern University has developed a prototype of a holographic camera that can see through objects. The new high-resolution camera can capture images through the human body, fog and around corners for vehicles.
The technology is known as synthetic wavelength holography, in which light emits from the camera and scatters on the object. The light then returns to the camera, where an algorithm processes the returned light to form the hidden object’s image. The camera can capture images of quick-moving objects, even of a heartbeat and small capillaries.
The research team says that though the technology is in the prototype phase, it has the potential to be used in numerous fields.
