In a recent breakthrough, researchers have developed a new imaging technique that could revolutionize optics. The technique, called lensless complex amplitude demodulation (CAD), is based on a set of algorithms that can accurately reconstruct an image from a single phase-shifted wavefront. This has the potential to open up new imaging possibilities, such as high-resolution imaging in areas with limited space or where traditional optics are infeasible. By relying on a single wavefront, the technique eliminates the need for bulky lenses and enables images to be captured and processed in real time. The researchers believe that this technique could revolutionize the field of optics, allowing for the development of new and innovative imaging systems.
