Aberration correction refers to techniques used to minimize distortions in images caused by optical imperfections. These imperfections can arise from various factors, such as lens shape or alignment, leading to blurriness or color fringing. By adjusting the optical system or using software algorithms, aberration correction enhances image clarity and accuracy. In fields like microscopy and astronomy, aberration correction is crucial for obtaining precise observations. For instance, in electron microscopy, specialized lenses are employed to correct spherical and chromatic aberrations, allowing scientists to visualize samples at the nanoscale. Similarly, telescopes utilize adaptive optics to counteract atmospheric distortions, improving the quality of celestial images.
