Aberrations eliminated after the fact

A computational software technique that corrects optical tomography aberrations after images have been made could replace hardware-based adaptive optics and bring real-time 3-D microscopic tissue imaging into focus for a broader population of users. Precision is a critical component for correctly diagnosing diseases. Optical aberrations, such as astigmatism or distortion, affect high-resolution tissue imaging, causing areas that should be in focus to become blurry or streaked. Aberrations in imaging can make points appear as slashes or blurs. Graphic image courtesy of Steven Adie....Read full article

    adaptive optics
    Adaptive optics (AO) is a technology used to improve the performance of optical systems by reducing the effects of atmospheric distortions. The Earth's atmosphere can cause light passing through it to experience distortions, resulting in image blurring and degradation in various optical applications, such as astronomical observations, laser communications, and imaging systems. Adaptive optics systems actively adjust the optical elements in real-time to compensate for these distortions. Key...
