If existing 3D cameras need special pixels, this new system is capable of converting common 2D sensors into 3D sensors (eliminating the need to build them from scratch).
At present, the measurement of the distance between objects with light is possible only with special lidar systems (particularly expensive), ie a solution that uses a laser that "shoots" a light on the objects and evaluates the return time to determine how far it is. .
One way to add 3D imaging to standard sensors is based on the use of a light source and a modulator, and the Stanford team solved the modulator problem by exploiting a phenomenon known as acoustic resonance.
According to the researchers, this solution could become the basis for a new type of compact, low-cost and energy-efficient lidar.
And if you are wondering what advantages normal users could have from the possibility of exploiting the 3D potential in photography, the answer is that they are different: for example, it would be possible to capture scenes and objects that other people could look at from a distance as if they were physically present.
And again, sportsmen could take advantage of special 3D applications to study the movements of their bodies and prevent possible injuries or the 3D support could be used to make the devices safer (just think of a feature such as face scanning to unlock the device).
In essence, there are various reasons for hoping that this team of researchers will be able to optimize this new technology for commercial use.
