The MIT is developing a laser able to see in the corner camera
The MIT Media Lab researchers have developed a new imaging technology that could in the future be used to see "through" barriers by using opaque walls, doors, soil or ceilings as reflective mirrors.
The camera in question uses a femtosecond laser that produces ultra-short pulses and allows reproducing images low resolution in three dimensions of a hidden object is outside the field of the camera. The experimental system is literally able to see an object hidden behind an obstacle using nook and cranny of the room.
In synthesis, the system works by taking rapid pulses with femtosecond lasers on a wall in front of the hidden object. Light bounces on the wall and then disperses. Part of this dispersed light will then come hitting the hidden object before dispersing again. Yet again, a small part of this light will bounce off the wall and find the path to the sensor of the camera.
Despite the low amount of light received by the sensor of the camera of MIT to each pulse, gusts are so fast that the camera can take action at a rate of the order of the picosecond. By slightly changing the angle of each pulse laser fire, the system is able to rebuild, using an algorithm, the geometry in 3D of the hidden object.
This new technology could term help cars smart to see in blind spots, help the rescuers when they are involved in disaster areas or secure military operations by allowing seeing the dangers in a front room even enter.
