Holograms as in Star Wars can become reality

The device was the result of the work of researchers from the Massachusetts Institute of Technology (MTI), FlexCompute, Stratchade University, New York Polytechnic Institute, Applied Nanotools, Rochester Institute and Research Laboratory of the US Air Force. All necessary studies took more than four years.

And they were not in vain – developed by the international group of scientists structurally spatial light modulator (SLM) in terms of reaction speed 10 times faster than any modern analogues.

According to the scientists of the MTI, to create a separate 3D-heading, you need to extremely accurately and quickly control the light. None of the existing technologies based on liquid crystals or microse -grinder can provide such opportunities.

To achieve the goal, the researchers studied the array of resonators – a field of photon crystals with cavities, in which light is reflected more than 100,000 times before going out. This process takes only one nanosecond, which is enough for the device to catch light and control its output, manipulating micropolines.

Researchers demonstrated a specially developed algorithm that forms the outgoing light into a beam that can be quickly and accurately directed in the right direction. The device controls light using a micro-light display.

As stated in the MTI, the possibility of high -precision control of a huge strip of light can allow you to create devices that can very quickly transmit huge volumes of information. In addition, the device has a huge number of applications:

  • In ultra -suffering ledar sensors for cars with autopilot;

  • In the field of brain scan – the resulting images of living tissues will have high resolution and will not have “noise”.

Researchers plan to create larger models of the device after improving the production process. These models can be used in quantum devices and promising solutions for visualizing the type of 3D-heads or scanners ..
