A camera that shoots through objects: a new development of engineers
The innovative device was presented to the world by researchers from Northwestern University. It is a camera that can function through a scattering medium (such as fog, human skin, or even skull bones).
The development is based on a special technology called "wave holography". The essence of her work is to scatter coherent light sources on hidden objects. This means that the light, after scattering, is able to return to the camera. After that, a special algorithm determines the shape of the detected object. It should be noted that this method is also suitable for detecting fast moving objects (car, heart, etc.).
So-called line-of-sight imaging is a new field of research. Thanks to the method, images of large objects are determined with maximum accuracy (down to submilimeters). The highest level of camera resolution ensures that images are transmitted through the layers of the skin, and even capillaries can be seen.
To achieve such an impressive result, the authors of the development created a light wave by combining waves from two lasers at the same time. It is easily adaptable to display a holographic image in a variety of preconditions.
Previous developments with similar capabilities did not allow taking pictures in good quality. The difference between the new technology and prototypes is in the level of its temporal and spatial resolution, as well as in a larger viewing angle. Due to this, the new camera displays both small objects in a small space and large objects at a great distance.
