Scientists have just made a breakthrough in optics: an optical phased array (OPA) that can quickly and accurately calibrate itself. This is an important milestone in the development of optical systems and will lead to a new era of high-precision, ultra-fast imaging. The OPA uses a combination of hundreds of tiny lenses to focus, steer, and shape light beams, allowing it to be used in a wide range of applications from biomedical imaging to autonomous vehicle navigation. The team has developed an algorithm that can quickly and accurately calibrate the OPA in just a few minutes, compared to the days or months typically needed with traditional methods. This breakthrough could pave the way for more efficient and cost-effective imaging systems.
