Researchers have invented a new way to align 3D semiconductor chips by shining a laser through concentric metalenses patterned on the chips to produce a hologram. Their work can help to lower the cost ...

Digital 3D scanners are revolutionary tools for measuring changes in orthodontics, periodontics, and tooth wear. While most studies focus on the accuracy of the 3D scanning process, obtaining the ...

We present and evaluate an approach to document alignment meant for efficiency and portability, as it relies on automatically extracted lexical translations and simple set-theoretic operations for the ...

[Left] Semiconductor layers are stacked using concentric metalenses as alignment marks. [Right] Light shines through these marks to project a hologram. The alignment or misalignment of the lenses ...
