According to Digital Trends, a perspective camera capable of capturing people or objects hidden behind a wall may be available. At present, scientists at the Mogridge Institute are working on research and development.
The camera uses a special shooting technique called non-line-of-sight imaging. Cameras using non-line-of-sight imaging technology can emit high-speed pulsed lasers when shooting. When the laser hits a wall or ceiling, it scatters and spreads to the surface of other objects. In the end, many photons will return to the position of the camera. According to the difference in the return time of the photons, the camera can digitally reconstruct the shooting space. The hidden people or objects behind the wall can be revealed in the reconstructed image.
In fact, the technology used in this camera was originally developed by the Massachusetts Institute of Technology and was demonstrated as early as 2012. Recently, the US Department of Defense Advanced Research Projects Agency (DARPA) showed interest in this technology and provided its related research team with US$4.4 million in funding, hoping to speed up the research process and promote the availability of perspective cameras.
It is understood that this technology was pioneered by Andreas Velten. Currently, he has left MIT (Massachusetts Institute of Technology) to lead researchers at the Mogridge Institute and the University of Wisconsin-Madison to continue to optimize the technology. The grant from DARPA will give the research team the opportunity to further explore the limiting factors of non-line-of-sight imaging and eventually develop more fully-featured hardware for market use.
According to Velten, the more light scattered, the more data the non-line-of-sight imaging camera can collect. However, the brightness of light after a lot of bounces will be greatly reduced, which requires the camera to have a very high sensitivity to capture a small number of poor photons.
In addition, Velten plans to use DARPA's funds to tap into this technology's potential in the first two years, and the next two years to develop mass-produced hardware.
The application of non-line-of-sight imaging technology has broad prospects. In addition to the military field, it can be used in areas such as search and rescue, shipwreck exploration, and even the drawing of moon pit images. However, for conventional photography, this technology will not bring any impact.
