How eye imaging technology could help robots and cars see better

Even though robots don't have eyes with retinas, the key to helping them see and interact with the world more naturally and safely may rest in optical coherence tomography (OCT) machines commonly found in the offices of ophthalmologists.

Less-wasteful laser-cutting

Laser-cutting is an essential part of many industries, from car manufacturing to construction. However, the process isn't always easy or efficient: Cutting huge sheets of metal requires time and expertise, and even the most ...
