Wavefront reconstruction is a technique used in optics and imaging to recover the original wavefront of a light signal that has undergone distortion or aberration. This can be caused by factors such as atmospheric turbulence, imperfections in optical systems, or other sources of noise. By analyzing the distorted wavefront and applying mathematical algorithms, the original wavefront can be reconstructed to improve the quality and resolution of images. This technique is commonly used in applications such as adaptive optics, astronomical imaging, and medical imaging. Wavefront reconstruction plays a crucial role in improving the accuracy and performance of optical systems, allowing for clearer and more detailed images to be obtained in various fields of research and technology.
