The use of deformable mirrors to correct unwanted optical aberrations in real time is helping applications ranging from astronomy to biophotonics and data storage, reports Neil Savage. Adaptive ...

Traditional optical systems rely on bulky glass lenses, which have limitations like chromatic aberrations, low efficiency at ...

Modern imaging systems, such as those used in smartphones, virtual reality (VR), and augmented reality (AR) devices, are ...

Instead, aspheric lenses ha ve a profile that changes in curvature across the surface. This type of lens is designed to reduce spherical and optical aberrations without the need for a multi-lens ...

2024.240085 , discusses how cascaded metasurfaces enable adaptive aberration corrections for focus scanning. Optical researchers have long dreamed of the perfect control over the focus of light ...

This is because optical resolution is not sufficient: contrast is also needed. For simplicity, in the following explanation I will refer only to the most important lens aberration, the spherical ...
