US development high performance holographic camera


Xinhua News Agency, November 23, “Reference News” On the 23rd, “Daily Mail” Website Report “can be developed by a holographic camera that can be developed.” The report summary is as follows:

A high-performance holographic camera has been developed, which is almost anything, including wall corners, fog, and even human muscles and bones.

This device developed by researcher at Northwestern University, Illinois, USA, has adopted a technology called “synthetic wavelength holographic photography”. The working principle of this technology is to indirectly scatter light into hidden objects, which then scattered again and returns the camera, and artificial intelligence in the camera is used to reconstruct the image of the original object.

This is a relatively new research area called non-viewpoint (NLOS) imaging, which can quickly capture a full field of view of large area regions. Its imaging accuracy reaches mido. With this resolution, the artificial smart camera can shoot something under the skin, even photographing the finest capillaries.

Because of its high resolution, this technique may also be used to image fast moving objects, such as a heart that is jumped in a chest or a street speeding car.

This technology has not only significantly potential in non-invasive medical imaging, but also has a wide range of application prospects, including the establishment of an automotive warning navigation system and industrial inspections performed in a closed space.

The first author of the thesis Florian Wilomitz said: “Our technology will bring new wave of imaging ability.”

Previously used non-visual imaging techniques to obtain hidden object images have encountered problems with low resolution and narrow perspective range. Other problems previously encountered also include scanning devices for a long time, or a large area of ​​probes can be measured to measure scattering light.

This new technique overcomes the above problems and can achieve imaging of other media such as skin and metal with higher resolution.

It combines high spatial resolution, high instantaneous resolution, small detection area, and high angle views. This means that such a camera can imaging the micro part of the closed space with a higher resolution, and hidden objects within a larger region.

The camera is still a prototype machine that requires up to 10 years to become commercial products, partly in obtaining medical approval takes time.
