wavefront coding

Wavefront coding is an imaging technique that enhances the focus quality of optical systems, like cameras or microscopes, without requiring precise lens adjustments. It works by adding a specially designed optical element that alters the incoming light waves, allowing them to capture sharper images at different distances in a single exposure. This method helps to improve clarity and depth of field, making it particularly useful in applications like microscopy and photography, where capturing detailed images across varying distances is essential. Ultimately, wavefront coding enables clearer and more versatile imaging with greater ease and efficiency.
