Over the past decades, engineers have introduced numerous technologies that rely on light and its underlying characteristics. These include photonic and quantum systems that could advance imaging, ...

MTF is a technique, trusted by optical designers, for objectively evaluating the image-forming capability of military optical systems. As reflective beam collimators can be used to replicate a target ...

For contemporary applications like LiDAR, free-space optical communication, augmented reality, and on-chip photonics, dynamic light steering is essential. Traditionally, this has been accomplished ...

A misalignment-tolerant multi-pass optical cavity boosts weak Raman signals, doubling path length and enabling stable, ...

Beams of light that can be guided into corkscrew-like shapes called optical vortices are used today in a range of applications. Pushing the limits of structured light, Harvard applied physicists in ...

These optical scanners comprise two separate, perpendicular planar mirrors that rotate independently. They are positioned in a manner wherein laser light bouncing off the first mirror (axis 1) ...
